Medium modification of hadron masses and the thermodynamics of hadron resonance gas model


الملخص بالإنكليزية

We study the effect of temperature (T) and baryon density ({mu}) dependent hadron masses on the thermodynamics of hadronic matter. We use linear scaling rule in terms of constituent quark masses for all hadrons except for light mesons. T and {mu} dependent constituent quark masses and the light mesons masses are computed using 2+1 flavor Nambu-Jona-Lasinio (NJL) model. We compute the thermodynamical quantities of hadronic matter within excluded volume hadron resonance gas model (EHRG) with these T and {mu} dependent hadron masses. We confront the thermodynamical quantities with the lattice quantum chromodynamics (LQCD) at {mu} = 0 GeV. Further, we comment on the effect of T and {mu} dependent hadron masses on the transport properties near the transition temperature.
