Abstract

We study the scaling behavior of the pseudocritical couplings for the chiral phase transition in two-flavor QCD. We show that all existing results from lattice simulations on lattices with the temporal extent N_\ensuremathτ=4,6, and 8 can be mapped onto a universal scaling curve. The relevant combination of critical exponents, \ensuremathβ\ensuremathδ, is consistent with the scaling behavior expected for a second-order phase transition with O(4) exponents. At present, the scaling according to the O(2) symmetry group can, however, not be ruled out.
