Particle Production within the Quark Meson Coupling Model
arXiv:0904.3837 · doi:10.1103/PhysRevC.80.014905
Abstract
Quark meson coupling (QMC) models can be successfully applied to the description of compact star properties in nuclear astrophysics as well as to nuclear matter. In the regime of hot hadronic matter very few calculations exist using the QMC model, in particular when applied to particle yields in heavy ion collisions. In the present work, we identify the free energy of the bag with the effective mass of the baryons and we calculate the particle production yields on a Au+Au collision at RHIC with the QMC model and compare them with results obtained previously with other relativistic models. A smaller temperature for the fireball, T=132 MeV, is obtained due to the smaller effective baryon masses predicted by QMC. QMC was also applied to the description of particle yields at SPS in Pb+Pb collisions.
