Abstract

We present recent results on the QCD equation of state with 2+1+1 flavors of highly improved staggered quarks (HISQ).We focus on three sets of ensembles with temporal extent N=6, 8 and 10, that reach up to temperatures of 967, 725 and 580 MeV, respectively. The strange and charm quark masses are tuned to the physical values and the light quarks mass is set to one fifth of the strange. This corresponds to a Goldstone pion of about 300 MeV.
