Abstract
Group-theoretic arguments are used to determine the dependence of two- point correlators of quark bilinears on the current quark masses. The leading difference between pi and delta correlators is found to be of order m(s) times a U(1)(A-) violating correlator. These general argume nts are consistent with Schaefer's observation that if U(1)A violation persists to high enough temperatures then the strange eta can be ligh ter than the non-strange one.
