Study of the crossover transition of a gas of extended hadrons

Abstract

We formulate a simple model for a gas of extended hadrons at zero chemical potential by taking inspiration from the compressible bag model. We show that a crossover transition qualitatively similar to lattice QCD can be reproduced by such a system by including some appropriate additional dynamics. Under certain conditions, at high temperature, the system consists of a finite number of infinitely extended bags, which occupy the entire space. In this situation the system behaves as an ideal gas of quarks and gluons.Comment: 2 pages, 1 figure - To appear in the conference proceedings for Quark Matter 2009, March 30 - April 4, Knoxville, Tennesse
