On the Polyakov loop in 2+1 flavor QCD    [PDF]

A. Bazavov, P. Petreczky

We study the temperature dependence of the renormalized Polyakov loop in 2+1 flavor QCD for temperatures T<210 MeV. We extend previous calculations by the HotQCD collaboration using the highly improved staggered quark action and perform a continuum extrapolation of the renormalized Polyakov loop. We compare the lattice results with the prediction of non-interacting static-light meson resonance gas, which largely captures the temperature dependence of the renormalized Polyakov loop up to T=210 MeV. Furthermore, we discuss the temperature dependence of light and strange quark condensates.
