Equation of state in (2+1) flavor QCD at hightemperatures

Abstract: We calculate the Equation of State at high temperatures in (2+1) flavor QCD using the highly improved staggered quark (HISQ) action. We study the lattice spacing dependence of the pressure at high temperatures using lattices with temporal extent N τ = 6, 8, 10 and 12 and perform continuum extrapolations. We also give a continuum estimate for the Equation of State up to temperatures T = 2 GeV, which are then compared with results of the weak-coupling calculations. We find reasonable agreement with the HTL calcu… Show more

“…In this ensemble the strange quark mass has been fine tuned to its physical value, and the pion mass gets the value 320 MeV in the continuum. This is only statistically significant 6 for r > 0.4r 1 ∼ 1/1.6 GeV −1 (see [8]).…”

“…Another motivation to use the data set I is that the β = 8.4 ensemble suffers from frozen topological charge in the Montecarlo evolution. It has been shown (see [8]) that the effects of frozen topology in different sectors are statistically irrelevant for r < 0.4r 1 ∼ 1/1.61 GeV −1 . Therefore, by using the data set I this problem is completely avoided.…”

“…Unsatisfying realizations of the latter hierarchy are usually subleading in the error budgets. Topological freezing (incorrect sampling of the QCD vacuum's topological sectors), which occurs on fine lattices, seems to have no significant impact on short distance quantities [402] used in determining α s (M Z ). For < 5% precision of the QCD Lambda parameter as required for reaching 1% accuracy of α s (M Z ) aimed at in the next decade, electroweak or isospin breaking effects can still be safely neglected.…”

“…The scaled pressure, entropy density and energy density of the QGP phase are supposed to increase with the temperature. However, lQCD calculations of the thermodynamic observables show [218], that the massless non-interacting limit can not be reached even at temperatures of T ∼ 1 GeV.…”
