Entropy in the Thermal Model
  A brief review of the Hadron Gas model with reference to high energy heavy ion collisions is presented. The entropy dependence on temperature and baryonic chemical potential is numerically calculated, together with the entropy distribution between baryons and mesons. The theoretical entropy for a QGP with equivalent parameters is also calculated. It is shown that at low temperatures the dominant entropy contribution comes from baryons, while at high energies the dominant contribution comes from mesons. The turnover from baryon to meson domination occurs at T approx 140 MeV, which corresponds to an energy domain of the AGS at Brookhaven National Laboratory.
