Transition temperature and the equation of state from lattice QCD, Wuppertal-Budapest results

Polyakov loop in2+1flavor QCD

“…1 and compared with the continuum results obtained using the stout action [14]. The two lattice extrapolated continuum results agree with each other, except for T = 140 MeV, where our results are larger by two standard deviations.…”

“…In the recent past the renormalized Polyakov loop has been calculated on the lattice in 2+1 flavor QCD with physical quark masses using improved staggered fermion formulation [7,8,[11][12][13][14]. Furthermore, using the stout improved staggered action continuum results for the renormalized Polyakov loop have been presented [14]. The aim of this paper is to study the renormalized Polyakov loop in the low-temperature and transition regions and to perform an independent continuum extrapolation using the highly improved staggered quark (HISQ) action [15].…”

Lattice QCD: bulk and transport properties of QCD matter

“…Such results have been obtained by the WB collaboration from imaginary µ B simulations: c 2 , ...c 6 have been fitted on the µ B −derivatives of p/T 4 for fixed temperature [19]. At µ B = 0, the QCD phase transition is an analytic crossover [20]; a pseudocritical temperature T c can be defined by looking at the inflection point or peak of some specific observables [21,22,23,24]. One can follow the change in their position as the chemical potential increases: this gives rise to a µ B −dependence of T c which can be expressed as:…”

QCD thermodynamics with continuum extrapolated Wilson fermions I

“…[8]. The line of constant physics used there was extended to the fine lattices in [9,33,34]. We used the bare strange masses for each given beta as were determined there.…”
