Quark Coalescence and Hadronic Equilibrium

High Energy Physics - Phenomenology 2007-05-23 v2

Abstract

In a simplified model we study how close can the result of a fast, non-equilibrium hadronization of quark matter in an expanding fireball come to hadronic composition in equilibrium. We present a chemical approach to the simple A+B --> C quark fusion, showing ideal equilibrium constrained by conservation laws, the fugacity parametrization, as well as linear and non-linear quark coalescence models as different approximations to this chemistry. It is shown that color confinement requires a quark density dependent hadronization cross section.
