Gluon production, cooling and entropy in nuclear collisions
arXiv:hep-ph/9711346 · doi:10.1103/PhysRevC.50.406
Abstract
We study the cooling (heating) of a glue-parton gas due to production (destruction) of particles and determine the associated production of entropy. We incorporate sharing of the system energy among a changing number of particles. We find that the entropy of an evolving glue-parton gas changes in an insignificant range once the initial high temperature state has been formed, despite a great change in particle number and temperature.
