Phase transition between a hadrons system and QGP from entropy evolution
Abstract
We look for a method to calculate the entropy of a hadrons system and a quark-gluon plasma (QGP) system. Then build a transport model to simulate the evolution from one to another. By calculating the entropy, a crossover between hadron to QGP can clearly show, so people can judge whether the system has reached equilibrium or whether there is new matter produced in high energy collisions.
