Discrepancy between hadron matter and quark-gluon matter in net charge transfer fluctuation

Abstract

A parton and hadron cascade model, PACIAE, is employed to investigate the net charge transfer fluctuation within $|\eta |$=1 in Au+Au collisions at $\sqrt{s_{NN}}$=200 GeV. It is turned out that the observable of net charge transfer fluctuation, $\kappa$, in hadronic final state (HM) is nearly a factor of 3 to 5 larger than that in initial partonic state (QGM). However, only twenty percent of the net charge transfer fluctuation in the QGM can survive the hadronization
