Deconfinement Phase Transition in an Expanding Quark system in Relaxation Time Approximation
Zhenwei Yang, Pengfei Zhuang
Abstract
We investigated the effects of nonequilibrium and collision terms on the deconfinement phase transition of an expanding quark system in Friedberg-Lee model in relaxation time approximation. By calculating the effective quark potential, the critical temperature of the phase transition is dominated by the mean field, while the collisions among quarks and mesons change the time structure of the phase transition significantly.
