The QCD Transition at Non-Vanishing Temperatures
Zoltan Fodor (University of Wuppertal and UC San Diego)

Abstract: The nature of the QCD transition for physical quark masses is determined by using lattice calculation and the continuum extrapolation is carried out. The transition is an analytic cross-over. The transition temperatures are also determined in the continuum limit for three different quantites: chiral susceptibility, strange quark number susceptibility and Polyakov loop. Since the transition is a cross over transition temperatures defined by different quantities are different, too. Special attention is payed to uncertainties of the lattice approach, most importantly to the continuum limit extrapolation.
