TLDR
A Monte Carlo event generator HIJING is developed to study jet and multiparticle production in high energy {ital pp, {ital pA}, and {ital AA} collisions, and a schematic mechanism of jet interactions in dense matter is described.
Abstract
Combining perturbative-QCD inspired models for multiple jet production with low ${p}_{T}$ multistring phenomenology, we develop a Monte Carlo event generator hijing to study jet and multiparticle production in high energy $\mathrm{pp}$, $\mathrm{pA}$, and $\mathrm{AA}$ collisions. The model includes multiple minijet production, nuclear shadowing of parton distribution functions, and a schematic mechanism of jet interactions in dense matter. Glauber geometry for multiple collisions is used to calculate $\mathrm{pA}$ and $\mathrm{AA}$ collisions. The phenomenological parameters are adjusted to reproduce essential features of $\mathrm{pp}$ multiparticle production data for a wide energy range ($\sqrt{s}=5\ensuremath{-}2000$ GeV). Illustrative tests of the model on $p+A$ and light-ion $B+A$ data at $\sqrt{s}=20$ GeV/nucleon and predictions for Au+Au at energies of the BNL Relativistic Heavy Ion Collider ($\sqrt{s}=200$ GeV/nucleon) are given.

Charged Particles p T Spectra and the Correlation between p T and all Charged Particles at √S = 900 GeV

TL;DR: In this article, the transverse momentum (pT) spectra, covering a region of 0.15 −10 −GeV/c, of charged particles as well as the correlation between the average transversal momentum and all charged particles (Nch) in pp collision at 900 −Gv/c are investigated.

Hadron-string cascade versus hydrodynamics in Cu+Cu collisions at √sNN = 200 GeV

TL;DR: In this paper, single particle spectra as well as elliptic flow in Cu+Cu collisions were investigated within a hadronic cascade model and an ideal hydrodynamic model, and the results showed that the transverse momentum spectra for charged hadrons are surprisingly comparable between these two models.

Nuclear shadowing and high-p{sub T} hadron spectra in relativistic heavy ion collisions

S.R. Klein, +1 more
- 18 Apr 2003 - 
TL;DR: In this article, the authors explore how nuclear modifications to the nucleon parton distributions affect production of high-p_T$ hadrons in heavy ion collisions and find that shadowing is a small effect and cannot explain the large observed suppression of highp_t_T $ hadrons.
