Description

We show that the observed excess of entropy in fireballs from heavy ion collisions near 1 GeV/nucleon (lab) can be explained by a modified pionic spectum. Measurements of the dependence of entropy on excitation energy could show a transition from nucleonic to quark matter at higher excitation energies. (orig.)
