Abstract:

We present the first measurement of a new correlation function of Fermion bilinears in finite temperature QCD with and without dynamical quarks in a quantum number channel in which non-trivial correlations are known to be present for purely gluonic operators. We find that the Fermion correlator vanishes for

T \ge 3T_c/2

, in agreement with the expectation for weakly interacting quarks in a quark-gluon plasma.
