Aspects of chiral transition in a Hadron Resonance Gas model

We study the chiral condensate for 2 + 1 flavor QCD with physical quarks within a non-interacting Hadron Resonance Gas (HRG) model. By including latest information on mass variation of hadrons concerning light quark mass, from lattice and perturbation theory, we show that it is possible to quite accurately account crossover transition even conventional HRG have calculated pseudocritical temperature T c =161.2±1.6 MeV curvature curve κ =0.0203(7). These are in very good agreement continuum extrapolated results obtained studies. also discuss limitations extending such calculations toward limit. Furthermore, effects non-resonant hadron interactions model its consequences regime dense baryonic matter where not currently available.
