On Equation of State at physical quark masses

Abstract

QCD equation of state is calculated in (2+1) flavor QCD at temperatures corresponding fermion action on lattices with temporal extent $N_τ=8$. The results are compared with previous calculations performed at twice larger values of the light quark masses as well as with results obtained from the resonance gas model calculation. The deconfining and chiral aspects of the QCD transition are also discussed
