Entropy of expanding QCD matter
Abstract
Description
Using the lattice QCD equation of state for an isentropically expanding fireball we follow the evolution of the effective number of particles in an ideal gas pV/T. This number reduces roughly to its third around the crossover temperature, which helps to circumvent the entropy obstacle inherent in quark coalescence models of the hadronization.
