Abstract

We present a study on the direct determination of the $\eta '$ mass on the full set of SESAM and T $\chi$ L QCD vacuum configurations with 2 active flavours of Wilson fermions, at $\beta = 5.6$ . We observe a definite dependency of the two-loop correlator on the topological charge sector.
