QCD thermodynamics with continuum extrapolated Wilson fermions I

Journal of High Energy Physics Aims and scope Submit manuscript

Abstract

QCD thermodynamics is considered using Wilson fermions in the fixed scale approach. The temperature dependence of the renormalized chiral condensate, quark number susceptibility and Polyakov loop is measured at four lattice spacings allowing for a controlled continuum limit. The light quark masses are fixed to heavier than physical values in this first study. Finite volume effects are ensured to be negligible by using approriately large box sizes. The final continuum results are compared with staggered fermion simulations performed in the fixed N t approach. The same continuum renormalization conditions are used in both approaches and the final results agree perfectly.
