PACIAE 2.0: An updated parton and hadron cascade model (program) for the relativistic nuclear collisions

Listed in Teesside University Research Data Repository

Description

Abstract

We have updated the parton and hadron cascade model PACIAE for the relativistic nuclear collisions, from based on JETSET 6.4 and PYTHIA 5.7 to based on PYTHIA 6.4, and renamed as PACIAE 2.0. The main physics concerning the stages of the parton initiation, parton rescattering, hadronization, and hadron rescattering were discussed. The structures of the programs were briefly explained.

In addition, some calculated examples were compared with the experimental data. It turns out that this model (... Title of program: PACIAE version 2.0 Catalogue Id: AEKI_v1_0 Nature of problem The Monte Carlo simulation of hadron transport (cascade) model is successful in studying the observables at final state in the relativistic nuclear collisions.

However the high pT suppression, the jet quenching (energy loss), and the eccentricity scaling of v 2 etc., observed in high energy nuclear collisions, indicates the important effect of the initial partonic state on the final hadronic state. Therefore better parton and hadron transport (cascade) models for the relativistic nuclear collisi ...
