Dynamical role of Polyakov loops in the QCD thermodynamics. Polyakov-NJL model with eight quark interactions. 3. THE RENORMALIZED POLYAKOV LOOP In [1] the renormalized free energy of a heavy quark pair is obtained by matching the lattice data to the T = 0 potential at short distances.

Based around postgraduate-level lectures given by the author, the material is suitable for both beginners and graduate students. Renormalization Scheme Dependence. The running couplings such as ?(E) depend not only on the energy scale E, but also on the specic rules we also depends on the renormalization scheme, ??(??) = ?(?). However, this dependence starts at the three-loop level; the one-loop and two-loop terms in We present a renormalization procedure for Polyakov loops which explicitly implements the fact that the renormalization constant depends only on the ultraviolet cutoff. Using this we study the renormalized Polyakov loops in all representations up to the 27 of the gauge group SU(3). We find RENORMALIZATION. Quantum Field Theory and Quantum Gravity. Functional integral, Feynman diagrams, renormalization. Gauge fixing at the quantum level. We investigate the properties of fakeons in quantum gravity at one loop. 't Hooft and Polyakov loops.

Similar and, in some respect, stronger results have been obtained by Gell-Mann and Low [2] who discovered the renormalization group equation: d = C1 2 + C2 3 + dlog r/a The catastrophic We simulate QCD with 2+1 flavors and almost physical quark masses using the highly improved staggered quark action (HISQ).We demonstrate that the entropy derived from the Polyakov loop is a good probe of color screening.
