PACIAE 2.2.1: An updated issue of the parton and hadron cascade model PACIAE 2.2

The parton and hadron cascade model PACIAE 2.2 (cf. Yan et al. (2018) [11]) has been upgraded to the new issue of 2.2.1 with chiral magnetic effect (CME). charge correlation parameter, ?ss ?os, which is typically used “detect” CME, calculated by in Au+Au Pb+Pb collisions, result consistent STAR ALICE data. As an example, employed mimic pseudorapidity distribution (dNch/d?) transverse momentum spectra (pT) charged particles non-central collisions at RHIC energy LHC energy. found partly affect final-state basic observables relativistic nuclear collisions. By this a more realistic dynamical evolution can be depicted.
