"From Quarks and Gluons to Hadrons: A Study of the QCD Phase Boundary"

Presented by Jens Braun, TRIUMF Canada

Friday, December 5, 2008, 2:00 pm — Small Seminar Room, Bldg. 510

I discuss chiral symmetry breaking in QCD with its underlying mechanisms in terms of quarks and gluons and show the chiral phase boundary in the plane of temperature and number of (massless) quark flavors obtained from a functional renormalization group approach. Moreover, the dependence of the phase transition temperature on the quark chemical potential is discussed. The subject of the last part of the talk is the deconfinement phase transition in Yang-Mills theory. The results obtained from a functional renormalization group approach for the order-parameter potential, namely the Polyakov-loop potential, are shown.
