Abstract:
We study the scaling behaviour of the pseudo-critical couplings for the chiral phase transition in two-flavour QCD. We show that all existing results from lattice simulations on lattices with temporal extent , 6 and 8 can be mapped onto a universal scaling curve. The relevant combination of critical exponents, , is consistent with the scaling behaviour expected for a second order phase transition with exponents. At present, scaling according to the symmetry group can, however, not be ruled out.- gauge field theory: SU(3)
