Abstract

Arguments are first presented to suggest that perturbative QCD calculations cannot account for the average transverse momentum of the dileptons observed in hadronic collisions at present energies. Regarding the complication as being due to the many gluon interactions in the initial state, a thermal parton model is considered which is a combination of the thermodynamical model and the usual parton model. With practically no free parameter the observed features of can be reproduced with the correct dependences on the incident energy and the mass and rapidity of the dileptons.

Quark--parton model with large parton k/sub T/

Technical Report Hwa, R C ; Matsuda, S ; Roberts, R G

The quark--parton model is generalized to allow for arbitrarily large parton k/sub T/. Since it is expected that < k/sub T/ > will rise with Q/sup 2/ in (highly virtual) photon mediated processes, this generalization is necessary to restore the applicability of the quark-parton model. By treating k/sub T/ as an essential kinematical variable, the introduction of a new scaling variable z is considered. Together with Bjorken's x variable, a unified kinematical description is given of the four distribution functions: hadron structure functions and jet decay functions for spacelike and timelike photons. The possibility of a simple interpolating universal functionmore »« less

Review of the theory and phenomenology of lepton pair production. [Review Drell-Yan mechanism, parton distribution, gluon radiation, quantum chromodynamics, transverse momentum]

Conference Hwa, R. C.

Recent experimental data and theoretical developments on the production of lepton pairs in hadron collisions are reviewed. With emphasis on the interplay between theory and experiment, the relevance of theoretical calculations to the data available at present energies is critically examined. The Drell--Yan mechanism is found to be phenomenologically dominant provided that the parton distribution functions contain effects of gluon radiation in a narrow cone. Explicit QCD perturbative calculations of the non-Drell--Yan type yield results that are apparently important at large transverse momenta, but are contradicated by subsequent data at 400 GeV and below. A consistent picture in the partonmore »« less

Dilepton radiation by vector mesons and off-shell partons in the hot and dense medium

Journal Article Linnyk, O ; Bratkovskaya, E L ; Cassing, W - AIP Conference Proceedings

According to the dynamical quasiparticle model (DQPM) - matched to reproduce lattice QCD results in thermodynamic limit, - the constituents of the strongly interacting quark-gluon plasma (sQGP) are massive and off-shell quasi-particles (quarks and gluons) with broad spectral functions. In order to address the electromagnetic radiation of the sQGP, we derive off-shell cross sections of qq-bar{yields}{gamma}*, qq-bar{yields}{gamma}*+g and qg{yields}{gamma}*q(q-barg{yields}{gamma}*q-bar) reactions taking into account the effective propagators for quarks and gluons from the DQPM. Dilepton production in In+In collisions at 158 AGeV is studied by implementing these processes into the parton-hadron-string dynamics (PHSD) transport approach. The microscopic PHSD transport approach describesmore »« less

Large-p/sub T/ processes in a nonscaling parton model. OITS-76. [Particle rapidity, cross sections]

Technical Report Hwa, R C ; Spiessbach, A J ; Teper, M J

A nonscaling parton model is proposed to describe the large transverse momentum processes in hadron collisions. The scale noninvariance behavior of the parton momentum distribution is deduced from the recent ep and ..mu..p deep inelastic scattering data where gross violation of scaling has been observed. Power-law breaking effects are parametrized and utilized in the large-p/sub T/ calculations. The basic subprocess in which the large angle scattering occurs is taken to be between the partons only. With the normalization as the only adjustable parameter in the theory, excellent fits of the pion and proton inclusive cross sections at large p/sub T/more »« less
Some recent developments in the recombination model

Conference Hwa, R C

A critical review of the recombination model for hadron production at low P/sub T/ is first given, emphasizing not so much the successes as unanswered questions that the model faces. A systematic program to answer some of the basic questions is then developed. The theoretical framework is quantum chromodynamics. First, in what may appear as a digression, the possibility of formation of valence quark clusters (called valons) in a nucleon due to gluon bremsstrahlung and quark-pair creation is considered. Evidences are found not only for the valons in neutrino scattering data, but also indications for their momentum distribution in amore »« less
