Free energy of a static quark-antiquark pair and the renormalized Polyakov loop in three flavor QCD

Free energy of a static quark-antiquark pair and the renormalized Polyakov loop in three flavor QCD

We study the free energy of a static quark-antiquark ($Q\overline{Q}$) pair at finite temperature in three flavor QCD with degenerate quark masses using ${N}_{\ensuremath{\tau}}=4$ and $6$ lattices with Asqtad staggered fermion action. The static free energy was calculated for different values of the quark mass and the entropy contribution at …
