Polyakov loop fluctuations in SU(3) lattice gauge theory and an effective gluon potential

Triangle Nuclear Theory Colloquium
Krzysztof Redlich (Wroclaw U.)

We discuss results on the Polyakov loop susceptibilities in SU(3)
lattice gauge theory. The longitudinal and transverse fluctuations of the
Polyakov loop, as well as, that of its absolute value will be introduced
in the context of the confinement-deconfinement phase transition.
We will indicate the influences of fermions
on the Polyakov loop fluctuations, based on lattice calculations in 2- and
(2+1)-flavors QCD. We show, that ratios of different susceptibilities of
the Polyakov loop are excellent probes of critical behavior. We will
formulate an effective model for the
Polyakov loop coupled to fermions and discus its applications to QCD
thermodynamics. We emphasize the role of fluctuations to fully explore
properties of QCD in the limit of heavy flavours.
