Color screening in a hot
quark-gluon-plasma
Johannes Weber (TU Munich)
Color
screening in a hot quark-gluon-plasma is the origin of deconfinement in
the high temperature phase of strongly interacting matter. After a brief
review of QCD at high temperature, I discuss color screening in lattice
QCD simulations of the Polyakov loop and of Polyakov loop correlators
with 2+1 flavors and almost physical quark masses.
I elucidate how the Polyakov loop and related observables behave in the
crossover region and how these observables provide a well-controlled
probe the deconfinement aspects of the crossover.
I examine Polyakov loop correlators, extract screening masses and
discuss the onset of weak-coupling behavior at high temperatures and
short distances.
