  Abstract: Neutrino production of radio Cherenkov signals in the Moon is the object of radio telescope observations. Depending on the energy range and detection parameters, the dominant contribution to the neutrino signal may come from interactions of the neutrino on the Moon facing the telescope, rather than neutrinos that have traversed a portion of the Moon. Using the approximate analytic expression of the effective lunar aperture from a recent paper by Gayley, Mutel and Jaeger, we evaluate the background from cosmic ray interactions in the lunar regolith. We also consider the modifications to the effective lunar aperture from generic non-standard model neutrino interactions. A background to neutrino signals are radio Cherenkov signals from cosmic ray interactions. For cosmogenic neutrino fluxes, neutrino signals will be difficult to observe because of low neutrino flux at the high energy end and large cosmic ray background in the lower energy range considered here. We show that lunar radio detection of neutrino interactions is best suited to constrain or measure neutrinos from astrophysical sources and probe non-standard neutrino-nucleon interactions such as microscopic black hole production. © 2011 Elsevier B.V.

  Abstract: The AdS/CFT correspondence in principle gives a new approach to deep inelastic scattering as formulated by Polchinski and Strassler. Subsequently Brower, Polchinski, Strassler and Tan (BPST) computed the strong coupling kernel for the vacuum (or Pomeron) contribution to total cross sections. By identifying deep inelastic scattering with virtual photon total cross section, this allows a self consistent description at small-x where the dominant contribution is the vacuum exchange process. Here we formulate this contribution and compare it with HERA small-x DIS scattering data. We find that the BPST kernel along with a very simple local approximation to the proton and current "wave functions" gives a remarkably good fit not only at large Q 2 dominated by conformal symmetry but also extends to small Q 2, supplemented by a hard-wall cut-off of the AdS in the IR. We suggest that this is a useful phenomenological parametrization with implications for other diffractive processes, such as double diffractive Higgs production. © 2010 SISSA.

  Abstract: We calculate contained and upward muon flux and contained shower event rates from neutrino interactions, when neutrinos are produced from annihilation of the dark matter in the Galactic center. We consider model-independent direct neutrino production and secondary neutrino production from the decay of taus, W bosons, and bottom quarks produced in the annihilation of dark matter. We illustrate how muon flux from dark matter annihilation has a very different shape than the muon flux from atmospheric neutrinos. We also discuss the dependence of the muon fluxes on the dark matter density profile and on the dark matter mass and of the total muon rates on the detector threshold. We consider both the upward muon flux, when muons are created in the rock below the detector, and the contained flux when muons are created in the (ice) detector. We also calculate the event rates for showers from neutrino interactions in the detector and show that the signal dominates over the background for 150GeV

  Abstract: We calculate the contained and upward muon and shower fluxes due to neutrinos produced via dark matter annihilation or decay in the Galactic center. We consider dark matter models in which the dark matter particle is a gravitino, a Kaluza-Klein particle and a particle in leptophilic models. The Navarro-Frenk-White profile for the dark matter density distribution in the Galaxy is used. We incorporate neutrino oscillations by assuming maximal mixing and parametrize our results for muon and shower distributions. The muon and shower event rates and the minimum observation times in order to reach 2σ detection significance are evaluated. We illustrate how observation times vary with the cone half angle chosen about the Galactic center, with the result that the optimum angles are about 10° and 50° for the muon events and shower events, respectively. We find that for the annihilating dark matter models such as the leptophilic and Kaluza-Klein models, upward and contained muon as well as showers are promising signals for dark matter detection in just a few years of observation, whereas for decaying dark matter models, the same observation times can only be reached with showers. We also illustrate for each model the parameter space probed with the 2σ signal detection in five years. We discuss how the shape of the parameter space probed change with significance and the observation time. © 2010 The American Physical Society.

  Abstract: Charm production gives rise to a flux of very high energy neutrinos from astrophysical sources with jets driven by central engines, such as gamma ray bursts or supernovae with jets. The neutrino flux from semileptonic decays of charmed mesons is subject to much less hadronic and radiative cooling than the conventional flux from pion and kaon decays and therefore has a dominant contribution at higher energies, which is of relevance to future ultrahigh energy neutrino experiments. © 2009 The American Physical Society.

  Abstract: We perform a detailed study of the Higgs production and decay, when Higgs is emitted from the black holes produced in proton-proton collisions at the Large Hadron Collider. We show that black hole production can significantly enhance the signal for the Higgs search at the LHC. We evaluate rapidity distribution of diphotons and transverse momentum distribution of bottom quarks, photons, tau leptons, top quarks, and W bosons from Higgs decay, when Higgs is emitted from the black hole and also in the case when these particles are produced directly from the black hole evaporation. We compare our results with the standard model backgrounds. We find that Higgs production from black holes is dominant over standard model production for pTH>100GeV, when MP=1TeV. Diphotons from Higgs, when Higgs is produced from evaporation of black holes, are dominant over the standard model prediction, for diphoton rapidity |yγγ|≤1, while bottom quarks are dominant over QCD background for large bottom quark transverse momentum, pTb>300GeV, when MP=1TeV. We show that measurements of the photon and bottom quark transverse momentum distribution can provide valuable information about the value of the fundamental Planck scale. We also propose a new signal for black hole production at the LHC, an onset of increasing transverse momentum distribution of bottom quarks with large transverse momentum. © 2009 The American Physical Society.

  Abstract: We calculate the muon flux from annihilation of the dark matter in the core of the Sun, in the core of the Earth and from cosmic diffuse neutrinos produced in dark matter annihilation in the halos. We consider model-independent direct neutrino production and secondary neutrino production from the decay of taus produced in the annihilation of dark matter. We illustrate how muon energy distribution from dark matter annihilation has a very different shape than muon flux from atmospheric neutrinos. We consider both the upward muon flux, when muons are created in the rock below the detector, and the contained flux when muons are created in the (ice) detector. We contrast our results to the ones previously obtained in the literature, illustrating the importance of properly treating muon propagation and energy loss. We comment on neutrino flavor dependence and their detection. © 2009 The American Physical Society.

  Abstract: Models of late-time neutrino mass generation contain new interactions of the cosmic background neutrinos with supernova relic neutrinos (SRNs). Exchange of an on-shell light scalar may lead to significant modification of the differential SRN flux observed at earth. We consider an Abelian U(1) model for generating neutrino masses at low scales, and show that there are cases for which the changes induced in the flux allow one to distinguish the Majorana or Dirac nature of neutrinos, as well as the type of neutrino mass hierarchy (normal or inverted or quasidegenerate). In some region of parameter space the determination of the absolute values of the neutrino masses is also conceivable. Measurements of the presence of these effects may be possible at the next-generation water Cerenkov detectors enriched with Gadolinium, or a 100 kton liquid argon detector. © 2007 The American Physical Society.

  Abstract: We study the signal for the detection of quasistable supersymmetric particle produced in interactions of cosmogenic neutrinos. We consider energy loss of high-energy staus due to photonuclear and weak interactions. We show that there are optimal nadir angles for which the stau signal is a factor of several hundred larger than muons. We discuss how one could potentially eliminate muon background by considering the energy loss of muons in the detector. We also show results for the showers produced by weak interactions of staus that reach the detector. © 2007 The American Physical Society.

  Abstract: We study ultrahigh energy astrophysical neutrinos and their interactions. We find that for GZK neutrinos three flavor mixing is important and the neutrino flavor ratio at Earth deviates from 1:1:1. We show the effect of tau neutrino regeneration and tau energy loss as they propagate through the Earth. We also consider production of mini black holes, neutrino interactions via TeV string resonances and the supersymmetric charged sleptons (stau) production in neutrino interactions.

  Abstract: In models in which neutrinos are light, due to a low scale of symmetry breaking, additional light bosons are generically present. We show that the interaction between diffuse supernova relic neutrinos (SRN) and the cosmic background neutrinos, via exchange of these light scalars, can result in a dramatic change of the supernova (SN) neutrinos flux. Measurement of this effect with current or future experiments can provide a spectacular direct evidence for the low scale models. We demonstrate how the observation of neutrinos from SN1987A constrains the symmetry breaking scale of the above models. We also discuss how current and future experiments may confirm or further constrain the above models, either by detecting the "accumulative resonance" that diffuse SRN go through or via a large suppression of the flux of neutrinos from nearby ≲ script O sign (Mpc) SN bursts. © SISSA 2006.

  Abstract: Neutrino telescopes may have the potential to detect the quasistable staus predicted by some supersymmetric models. Detection depends on stau electromagnetic energy loss and weak interactions. We present results for the weak interactions contribution to the energy loss of high energy staus as they pass through rock. We show that the neutral-current weak interaction contribution is much smaller than photonuclear energy loss, however, the charged-current contribution may become dominant process above an energy of ∼109GeV. As a consequence, the stau range may be reduced above ∼109GeV as compared to the range neglecting weak interactions. We contrast this with the case of tau range, which is barely changed with the inclusion of charged-current interactions. © 2006 The American Physical Society.

  Abstract: The potential for neutrino telescopes to discover charged stau production in neutrino-nucleon interactions in Earth depends in part on the stau lifetime and range. In some supersymmetric scenarios, the next lightest supersymmetric particle is a stau with a decay length on the scale of 10 km. We evaluate the electromagnetic energy loss as a function of energy and stau mass. The energy loss parameter β scales as the inverse stau mass for the dominating electromagnetic processes, photonuclear and e+e- pair production. The range can be parameterized as a function of stau mass, initial energy and minimum final energy. In comparison to earlier estimates of the stau range, our results are as much as a factor of two larger, improving the potential for stau discovery in neutrino telescopes. © 2005 Elsevier B.V.

  Abstract: The ultrahigh energy neutrino cross section is well understood in the standard model for neutrino energies up to 1012 GeV. Tests of neutrino oscillations (νμ ↔ ντ) from extragalactic sources of neutrinos are possible with large underground detectors. Measurements of horizontal air shower event rates at neutrino energies above 1010 GeV will be able to constrain nonstandard model contributions to the neutrino-nucleon cross section, e.g., from mini-black hole production.

We find the nextto-leading order corrections to be large and pT dependent. We show how measurements of π0 production at RHIC and LHC, at large pT, can provide valuable information about the nature of parton energy loss. We calculate the ratio of prompt photons to neutral pions and show that at RHIC energies this ratio increases with pT approaching one at p T ∼ 10 GeV, due to the large suppression of π0 production. We show that at the LHC, this ratio has steep pT dependence and approaches 10% effect at pT ∼ 20 GeV.

  Abstract: We present results for inclusive π0 production in proton-proton and in Au-Au at RHIC energy √s = 200 GeV. We use next-to-leading order perturbative QCD calculation and we include nuclear effects such as parton energy loss and nuclear shadowing. We consider the ratio of π0 distribution in Au-Au and p-p collisions for pT > 3 GeV for three cases of parton energy loss: (1) constant parton energy loss per parton scattering, εna = const, (2) Landau-Pomeranchuk-Migdal energy-dependent energy loss, εna ∼ √Ena and (3) Bethe-Heitler energy-dependent energy loss, εna ∼ Ena. We show that recently observed suppression of π0 production in Au-Au collisions at RHIC, which is found to increase with pT increasing from 3 GeV to 8 GeV, can be reproduced by εna = 0.06Ena. We show that the ratio of prompt photons to neutral pions produced in Au-Au collisions at RHIC has a strong pT dependence approaching one at pT ∼ 10 GeV. © 2003 Published by Elsevier Science B.V.

  Abstract: In models with several large extra dimensions and fundamental Planck scale of the order of 1 TeV, black holes can be produced in large numbers at LHC energies. We compute the charged hadron spectra obtained from the decay of black holes created in pp and Pb + Pb collisions at LHC. We show that hadrons from black hole decay dominate at transverse momenta pT ≳ 30-100 GeV/c compared to usual QCD processes and black hole production signals are easy to identify in hadron transverse momentum spectra. Furthermore we show that a measurement of the charged hadron spectra probes Planck scales up to 5 TeV for any number of extra dimensions. © 2003 Published by Elsevier Science B.V.

  Abstract: In scenarios with large extra dimensions and TeV scale gravity, ultrahigh energy neutrinos produce black holes in their interactions with the nucleons. We show that OWL may observe a large number of black hole events and provide valuable information about the fundamental Planck scale and the number of extra dimensions. OWL is especially well suited to observe black hole events produced by neutrinos from the interactions of cosmic rays with the 3 K background radiation. Depending on the parameters of the scenario of large extra dimensions and on the flux model, as many as 28 events per year are expected for a Planck scale of 3 TeV. © 2002 The American Physical Society.

  Abstract: The energy dependence of "secondary" neutrinos from the process (vτ→τ-→v̄μ→μ̄) for two input tau neutrino fluxes (Fv0∼Ev-1 and Ev-2), assumed to have been produced via neutrino oscillations from extragalactic sources, is evaluated to assess the impact of secondary neutrinos on upward muon rates in a km3 detector. We show that the secondary fluxes are considerably suppressed for the steeper flux, and even for fluxes ∼Ev-1 the secondary flux will be difficult to observe experimentally. © 2002 The American Physical Society.

  Abstract: We present a detailed study of prompt photon production cross section in heavy-ion collisions in the central rapidity region at energy of √s = 5.5 TeV, appropriate to LHC experiment. We include the next-to-leading order radiative corrections, O(αemα2s), nuclear shadowing and the parton energy-loss effects.

  Abstract: We demonstrate that sizable neutrino flavor oscillations can be generated in a model with large extra spacetime dimensions even if the physics on the brane is flavor-diagonal, the bulk neutrino theory is flavor-neutral, and the brane/bulk couplings are flavor-blind. This is thus a compact model for addressing neutrino flavor oscillations in higher dimensions. We also discuss several phenomenological aspects of the "bulk-mediated" neutrino oscillations inherent in this model, and show that this model contains some potentially important new phenomenological features in the limit of large brane/bulk coupling. © 2001 Published by Elsevier Science B.V.

  Abstract: We evaluate the upward shower and muon event rates for two characteristic four neutrino mixing models for extragalactic neutrinos, as well as for the atmospheric neutrinos, with energy thresholds of 1 TeV, 10 TeV and 100 TeV. We show that by comparing the shower to muon event rates, one can distinguish between oscillation and no-oscillation models. By measuring shower and muon event rates for energy thresholds of 10 TeV and 100 TeV and by considering their ratio, it is possible to use extragalactic neutrino sources to determine the type of four-flavor mixing pattern. We find that over several years of data taking, a kilometer-size detector has a very good chance of providing valuable information about the physics beyond the standard model. ©2001 The American Physical Society.

  Abstract: The photonuclear contribution to charged lepton energy loss has been reevaluated taking into account DES Y HERA results on real and virtual photon interactions with nucléons. With large Q2 processes incorporated, the average muon range in rock for energies of 109 GeV is reduced by only 5% compared with the standard treatment. We have calculated the tau energy loss for energies up to 109 GeV taking into consideration the decay of tau. A Monte Carlo evaluation of tau survival probability and range shows that at energies below 107-108 GeV, depending on the material, only tau decays are important. At higher energies the tau energy losses are significant, reducing the survival probability of the tau. We show that the average range for tau is shorter than its decay length and reduces to 17 km in water for an incident tau energy of 109 GeV, as compared with its decay length of 49 km at that energy. In iron, the average tau range is 4.7 km for the same incident energy. ©2001 The American Physical Society.

  Abstract: We calculate the inclusive cross section for prompt photon production in heavy-ion collisions at RHIC energies (√s = 130 GeV and √s = 200 GeV) in the central rapidity region including next-to-leading order, O(αemα2s), radiative corrections, initial state nuclear shadowing, and parton energy loss effects. We show that there is a significant suppression of the nuclear cross section, up to ∼30% at √s = 200 GeV, due to shadowing and medium induced parton energy loss effects. We find that the next-to-leading order contributions are large and have a strong pt dependence.

  Abstract: The appearance of high energy tau neutrinos due to νμ→ντ oscillations of extragalactic neutrinos can be observed by measuring the neutrino induced upward hadronic and electromagnetic showers and upward muons. We evaluate quantitatively the tau neutrino regeneration in the Earth for a variety of extragalactic neutrino fluxes. Charged-current interactions of the upward tau neutrinos below and in the detector, and the subsequent tau decay, create muons or hadronic and electromagnetic showers. The background for these events are muon neutrino and electron neutrino charged-current and neutral-current interactions, where in addition to extragalactic neutrinos, we consider atmospheric neutrinos. We find significant signal to background ratios for the hadronic combined with electromagnetic showers with energies above 10-100 TeV initiated by the extragalactic neutrinos. We show that the tau neutrinos from point sources also have the potential for discovery above a 1 TeV threshold. A kilometer-size neutrino telescope has a very good chance of detecting the appearance of tau neutrinos when both muon and hadronic combined with electromagnetic showers are detected. ©2000 The American Physical Society.

  Abstract: We propose a novel approach for studying vμ→vτ oscillations with extragalactic neutrinos. Active galactic nuclei and gamma ray bursts are believed to be sources of ultrahigh energy muon neutrinos. With distances of 100 Mpc or more, they provide an unusually long baseline for possible detection of vμ→vτ with mixing parameters Δm2 down to 10-17 eV2, many orders of magnitude below the current accelerator experiments. By solving the coupled transport equations, we show that high-energy vτ's, as they propagate through the Earth, cascade down in energy, producing the enhancement of the incoming vτ flux in the low energy region, in contrast with the high-energy vμ's, which get absorbed. For an AGN quasar model we find the vτ flux to be a factor of 2 to 2.5 larger than the incoming flux in the energy range between 102 GeV and 104 GeV, while for a GRB fireball model, the enhancement is 10-27 % in the same energy range and for zero nadir angle. This enhancement decreases with larger nadir angle, thus providing a novel way to search for vτ appearance by measuring the angular dependence of the muons. To illustrate how the cascade effect and the vτ final flux depend on the steepness of the incoming vτ, we show the energy and angular distributions for several generic cases of the incoming tau neutrino flux, Fv0∼E-n for n=1, 2 and 3.6. We show that for the incoming flux that is not too steep, the signal for the appearance of high-energy vτ is the enhanced production of lower energy μ and their distinctive angular dependence, due to the contribution from the τ decay into μ just below the detector. ©2000 The American Physical Society.

  Abstract: EGRET onboard the Compton Gamma Ray Observatory has recently detected a high-energy source at the Galactic center. However, it is not yet clear whether the γ-rays are produced by the hypothesized massive black hole, Sgr A*, or whether the emitter is diffuse. The lack of variability in the γ-ray flux, up to an amplitude of about 20%, seems to suggest the latter. But hydrodynamical simulations of the accretion process point to a fluctuation amplitude in the inflowing mass rate below this level on a timescale comparable to the current observation time line. Thus, if the γ-ray flux is directly tied to the dissipation of gravitational energy, e.g., if it is produced by relativistic particles energized by a shock within the infalling plasma, we cannot rule Sgr A* out as the source of the γ-rays on this basis alone. In earlier work, we demonstrated that the γ-ray spectrum from the Galactic center may be consistent with the radiative decay of pions produced via proton-proton interactions in this shock acceleration scenario. However, this study was incomplete for several reasons. In this paper, we extend this work significantly by making several improvements to our treatment of the particle physics. We also make use of the new EGRET data published since our last paper. Our analysis now indicates that the hypothesized massive black hole is probably not the source of the γ-rays. Understanding the nature of the Galactic center γ-ray source may ultimately depend on whether or not future γ-ray detectors will have the capability of resolving it. In this paper we consider a point source, but if the γ-rays are in fact associated with diffuse emission, GLAST may be able to image the source with a spatial resolution of ∼ 30″ to 5′.

  Abstract: We investigate the nuclear shadowing mechanism in the context of perturbative QCD and the Glauber-Gribov multiple scattering model. Using recent HERA data on nucleon structure function at small x, we put stringent constrains on the nucleon gluon density in the double-logarithm approximation. We suggest that the scaling violation of the nucleon structure function in the region of small-x and semihard scale Q2 can be reliably described by perturbative QCD which is a central key to the understanding of the scale dependence of the nuclear shadowing effect. Our results indicate that while the shadowing of the quark density arises from an interplay between "soft" and semihard QCD processes, while gluon shadowing is largely driven by a perturbative shadowing mechanism. We demonstrate that the gluon shadowing is a robust phenomenon at large Q2 and can be unambiguously predicted by perturbative QCD. © 1998 Elsevier Science B.V.

  Abstract: We present a calculation of the fluxes of muons and muon neutrinos from the decays of pions and kaons that are themselves the decay products of charmed particles produced in the atmosphere by cosmic ray-air collisions. Using the perturbative cross section for charm production, these lepton fluxes are two to three orders of magnitude smaller than the fluxes from the decays of pions and kaons directly produced in cosmic ray-air collisions. Intrinsic charm models do not significantly alter our conclusions for E < 103 GeV. Models with a charm cross section enhanced in the region above an incident cosmic ray energy of 103 GeV give enhanced lepton fluxes above 104 GeV, a region in which prompt muons dominate over the secondary decay contributions. © 1998 Elsevier Science B.V.

  Abstract: We calculate the dilepton emissions as the decay product of the charm and bottom quarks produced in heavy-ion collisions at RHIC energy. We take into account the next-to-leading-order radiative corrections in perturbative QCD to the heavy quark production from an initial hard parton-parton scattering. We find that the thermal charm decay dominates the dilepton production in the low dilepton mass region (2 GeV). Our result also indicates the importance of the bottom quark in the high mass region (>4 GeV) due to its large mass and cascade decay. If the initial scattering produced charm suffers a significant energy loss due to the secondary interaction, the bottom decay constitutes the major background for the thermal dileptons.

  Abstract: The recent detection of a γ-ray flux from the direction of the Galactic center by EGRET on the Compton GRO raises the question of whether this is a point source (possibly coincident with the massive black hole candidate Sgr A*) or a diffuse emitter. Using the latest experimental particle physics data and theoretical models, we examine in detail the γ-ray spectrum produced by synchrotron, inverse Compton scattering, and mesonic decay resulting from the interaction of relativistic protons with hydrogen accreting onto a point-like object. Such a distribution of high-energy baryons may be expected to form within an accretion shock as the inflowing gas becomes supersonic. This scenario is motivated by hydrodynamic studies of Bondi-Hoyle accretion onto Sgr A*, which indicate that many of its radiative characteristics may ultimately be associated with energy liberated as this plasma descends into the deep potential well. Earlier attempts to analyze this process concluded that the EGRET data are inconsistent with a massive point-like object. Here we demonstrate that a more careful treatment of the physics of p-p scattering suggests that a black hole of ∼106 M⊙ may be contributing to this high-energy emission. © 1997.

  Abstract: We present a novel method for studying the formation of a disoriented chiral condensate (DCC) in high energy heavy-ion collisions utilizing a discrete wavelet transformation. Because of its salient feature of space-scale locality, the discrete wavelet proves to be very effective in probing physics simultaneously at different locations in phase space and at different scales. We show that the probability distributions of the neutral pion fraction for various rapidity-bin sizes have distinctive shapes in the case of a DCC and exhibit a delay in approaching the Gaussian distribution required by the central limit theorem. We find the wavelet power spectrum for a DCC to exhibit a strong dependence on the scale while an equilibrium system and the standard dynamical models such as HIJING have a flat spectrum.

In such events, the pT spectrum of charged hadrons from jet fragmentation in the direction opposite to the tagged photon is estimated to be well above the background which can be reliably subtracted at moderately large pT. We demonstrate that comparison between the extracted fragmentation function in AA and pp collisions can be used to determine the jet energy loss and the interaction mean free path in the dense matter produced in high-energy heavy-ion collisions.

  Abstract: We reexamine the theory of hadronic photon-nucleon interactions at the quark-gluon level. The possibility of multiple parton collisions in a single photon-nucleon collision requires an eikonal treatment of the high-energy scattering process. We give a general formulation of the theory in which the γp cross section is expressed as a sum over properly eikonalized cross sections for the interaction of the virtual hadronic components of the photon with the proton, with each cross section weighted by the probability with which that component appears in the photon, and then develop a detailed model which includes contributions from light vector mesons and from excited virtual states described in a quark-gluon basis. The parton distribution functions which appear can be related approximately to those in the pion, while a weighted sum gives the distribution functions for the photon. We use the model to make improved QCD-based predictions for the total inelastic photon-nucleon and photon-nucleus cross sections at energies relevant for DESY HERA experiments and cosmic-ray observations. We emphasize the importance in this procedure of including a soft-scattering background such that the calculated cross sections join smoothly with low-energy data. Our results show clearly that high-energy measurements of the total inelastic γp cross section can impose strong constraints on the gluon and quark distributions in the photon, and indirectly on those in the pion. © 1993 The American Physical Society.

  Abstract: We evaluate the strength of rapidity correlations as measured by bin-averaged multiplicity moments for hadron-hadron, hadron-nucleus, and nucleus-nucleus collisions for comparable c.m. energies s 20 GeV. The strength of the correlation decreases rapidly with increasing complexity of the reaction. Although statistically significant cumulant moments, K2, K3, and K4 are found in hadron-hadron (NA22) collisions, higher moments are strongly suppressed (except for K3 in KLM Collaboration proton-emulsion data) when nuclei are involved. When ordinary factorial moments are decomposed into cumulant moments, the former are seen to be dominated by combinatoric contributions of the (experimentally determined) cumulant moment K2. Hence rapidity fluctuations and intermittent effects are significantly decreased by the use of nuclei as targets and/or projectiles. This result could possibly be reversed at the onset (at higher energy) of a new phase having strong fluctuations, for example, the long-sought quark-gluon plasma. © 1991 The American Physical Society.

  Abstract: The close connection between factorial moments and factorial correlators as integrals of the same underlying correlation function is explored, leading to extensions of sum rules previously suggested. Cumulants, which were previously found to be the fundamental building blocks for moments, have been analogously defined for the correlators also, revealing the true n-particle correlations. Decomposing the factorial correlators into cumulants, we find that the largest part of the correlators consists of two-particle correlations for NA22 data. The nonstationarity of the correlation function is found to affect the results to a surprisingly small degree. It is pointed out that all linking schemes for higher-order correlations must be tested not on the correlators but on the cumulants in order to claim success. Finally, applying our scheme to UA1 factorial moment data, we predict the size and shape of UA1 correlators. © 1991 The American Physical Society.

  Abstract: We present results of calculations of the total and jet photon-proton cross sections at energies of relevance to the Fermilab E683 experiment and the ZEUS and H-1 experiments at the DESY ep collider HERA. The calculations take into account the high-energy QCD structure of the photon and are performed for two different photon structure functions. We discuss how these forthcoming experiments may be able to provide important information on two major uncertainties inherent to the calculation of photoproduction cross sections in particular and in a more general context, to the nature of strong interactions. If the total photoproduction cross section is measured at E683 energies (s =1628 GeV), it will provide a firmer value for pTmin, the lower bound on the transverse momentum of outgoing jets, which signals the onset of hard scattering. At HERA energies (s up to 300 GeV), the total and jet cross sections will help determine the photon structure function better at low-x (the fractional parton momentum) values, currently a region where there are large uncertainties due to a lack of data. © 1991 The American Physical Society.

  Abstract: We show that the observed increase of the factorial multiplicity moments with decreasing size of the rapidity bin (the so-called "intermittency" phenomenon) is a consequence of the short range correlations. With the linked-pair ansatz for higher order correlations, we find all the moments to be in a very good agreement with the NA22 and UA5 data. At very high energies, and in the large rapidity region, we find that self-similar cascade leads to a power-law behavior of the moments, in agreement with the UA5 data. We propose further tests of this particular mechanism for multiparticle production at Tevatron energies. © 1991.

  Abstract: We show that the KNO scaling violation in the parton branching model is due to the increase of the gluon contribution to the hadronic multiplicities. This results in the widening of the probability distribution in agreement with experimental data. We also find excellent agreement with experimental data on multiplicity moments in different rapidity regions. We present theoretical predictions for the multiplicities and moments at the Tevatron energies. We also show that QCD minijet cross section with pTmin of order 3 GeV and K factor of order 2 gives a very good description of the minijet data. We extrapolate our theoretical predictions to Tevatron energies indicating that measurements of the minijet production at these energies will have some resolving power to distinguish between different sets of structure functions. © 1990.

  Abstract: We show that in the parton branching model, the probability distribution does not obey KNO scaling. As energy increases, gluon contribution to multiplicities increases, resulting in the widening of the probability distribution, in agreement with experimental data. We predict that the widening of the distribution will stop at Tevatron Collider energies due to the dominant role of gluons at these energies. We also find that the gluon contribution to the "minijet" cross section increases with energy and becomes dominant at the Tevatron Collider. We calculate QCD minijet cross sections for a variety of structure functions, QCD scales and pTmin. We compare our theoretical results with the experimental data and find that some of the structure functions and choices of scale are preferred by the experimental data. We give theoretical predictions for the minijet cross section at the Tevatron Collider, indicating the possibility of distinguishing between different sets of structure functions and choices of scale. © 1989.

  Abstract: We show that a self-similar multihadron production pattern leads at high energies to a universtal law bahavior for the multiplicity moments as a function of the relative rapidity Y δy. Such behaviour occurs for Y → ∞ and δy larger than the scale associated with the usual resonance correlations: δy≥1-2. UA5 data for s = 200, 546 and 900 GeV are found to agree very well with the predicted universal behaviour. © 1989.

  Abstract: We propose a way to test structure functions at low x by measuring the heavy-quark cross section at Fermilab Tevatron Collider energies. We show that the QCD calculation (through order +s3) of the total cross section for the bottom- and top-quark pair cross section is very sensitive to the choice of the structure function at Collider energies. Comparison with the experimental data indicates that some choices of the structure functions seem to be preferred by the data. We illustrate how measurements of the bottom-quark pair cross section at Tevatron Collider energies should be able to make a clear distinction between different choices of the structure functions, therefore providing valuable information about the gluon structure function at low x. We find that the bottom-quark cross section at Collider energies is dominated by the gg initial subprocess, while the top-quark cross section is dominated by the contribution from the qq subprocess at low energies. At Tevatron energies this contribution becomes 30%, while the rest is due to the gg initial subprocess. We show that the ratio of the cross section calculated through order s3 to the one calculated through the order s2, the so-called K factor, is of order 3 for the bottom-quark cross section and of order 2 for the top-quark cross section at Tevatron energies. We also show that the theoretical uncertainty due to the choice of the structure function has a significant effect on the experimental lower limit of the top-quark mass. © 1989 The American Physical Society.

  Abstract: We calculate the lowest-order QCD jet cross section for a variety of different sets of structure functions, QCD scales, and parton minimum transverse momentum pTmin. We compare our theoretical results with the experimental data for the jet differential and total cross sections including the minijet regime in order to study the correlations between the various parameters. We find that for a constant K factor the choice of scale Q2=pT2 provides the best representation of the experimental data. With a K factor of order 2, a theoretical cutoff of pTmin3 GeV seems to describe the observed total minijet cross section with ETjet (ETraw)5 GeV. We extrapolate our results to yield predictions for the expected minijet cross section at the Fermilab Tevatron Collider which should have some resolving power to distinguish the different sets of structure functions and choices of scale. © 1989 The American Physical Society.

  Abstract: We consider a one-dimensional Feynman-Wilson "gas" as a statistical model for the multiparticle production in hadron-hadron collision. The Ginzburg-Landau probability functional introduced by Scalapino and Sugar not only gives a simple model of rapidity correlations but permits one to study the effect of phase transitions in the system. We show that in the constant field approximation, there is KNO scaling at very large energies. We also investigate the fluctuations around the mean field for T Tc. When T≅Tc, there is a first-order phase transition and the probability distribution has KNO scaling. We argue that the onset of KNO scaling is an indication of a transition of a hadronic matter to a quark-gluon plasma. Finally we give predictions for the observable quantities such as multiplicities, moments and two-particle correlations. © 1987.

  Abstract: We present multiplicity distributions which are solutions to branching equations, based on the assumption that the shapes and energy dependence of multiplicity distributions are principally determined by hard parton scattering and subsequent branching. We consider the four processes g gg, q qg, g qq, and in a few cases g ggg. All vertex probabilities for these processes are taken to be constant. In this simple approximation, we find that Koba-Nielsen-Olesen scaling is systemically violated. We compare the properties of branching distributions with the properties of the widely used negative-binomial distribution and of the stochastic approach. © 1987 The American Physical Society.

  Abstract: It is shown that the parton branching distribution Pmn of m quarks and n gluons does not obey exact Kobu-Nielsen-Olesen scaling. When the quark evolution is neglected the probability distribution becomes wider as energy increases in agreement with experimental data. In this model it is predicted that the widening of the probability distribution will stop at Fermilab Tevatron Collider energies (16002000 GeV). Also given are theoretical predictions for the multiplicities and moments for Tevatron Collider energies. © 1987 The American Physical Society.

  Abstract: It is shown that parton branhing equations for the probability Pmn of m quarks and n gluons have exact solutions which violate KNO scaling. Only the approximate solution is exactly a KNO function. Corrections to this approximate solution approach KNO scaling from below in the high-z tail, in agreement with recent collider data and in contrast to the negative binomial distribution. © 1986.
