Influence of the Pauli principle on the dynamics of the Quark-Gluon Plasma

Abstract

A simple parton cascade model for the ultra-relativistic nucleus-nucleus collisions is proposed to investigate the Pauli blocking at the transition from hadronic to partonic state, i.e. QGP. A boost invariant study of the Pauli blocking is implemented in the Monte Carlo simulation for the first time. It turns out that the higher reaction energy the stronger the partonic Pauli effect is. It amounts to about ten percent at SPS and RHIC energies but nearly reaches twenty percent at LHC energy. Thus the effect is relevant to the formation and evolution of the quark-gluon plasma.
