Abstract
We investigate the physical consequences of the survival of the effects of the anomaly in the chiral symmetric phase of , and show that the free energy density is a singular function of the quark mass , in the chiral limit, and that the and susceptibilities diverge in this limit at any . We also show that the difference between the and susceptibilities diverges in the chiral limit at any , a result which seems to be excluded by recent results of Tomiya et al. from numerical simulations of two-flavor QCD. We also discuss on the generalization of these results to the model.
