Description

Abstract We have updated the parton and hadron cascade model PACIAE 2.0 (cf. Ben-Hao Sa, Dai-Mei Zhou, Yu-Liang Yan, Xiao-Mei Li, Sheng-Qin Feng, Bao-Guo Dong, Xu Cai, Comput. Phys. Comm. 183 (2012) 333.) to the new issue of PACIAE 2.1. The PACIAE model is based on PYTHIA. In the PYTHIA model, once the hadron transverse momentum p T is randomly sampled in the string fragmentation, the p x and p y components are originally put on the circle with radius p T randomly. Now it is put on the circumference o... Title of program: PACIAE version 2.1 Catalogue Id: AEKI_v2_0 Nature of problem PACIAE is based on PYTHIA. In the PYTHIA model, once the generated particle/parton transverse momentum (p T ) is randomly sampled, the p x and p y components are randomly placed on the circle with radius of p T . This strongly cancels the final state transverse momentum asymmetry developed from the initial spatial asymmetry.
