QGP generation and evolution simulation of pp collision on LHC

Abstract

In this paper, the generation of Quark-Gluon Plasma(QGP) in proton–proton collisions is discussed based on the thermal equilibrium theory. A partons list at the initial stage of collisions are obtained by digital sampling method, which provides a reasonable initial state for the subsequent evolution simulation. The calculation shows that the multiplicity distribution of the final charged particles obtained by this method is very similar to that of experiment or PYTHIA event generator. Thus, a new mechanism for hadron production in LHC is proposed.
