We present a study of the topological susceptibility chi on the lattice for full QCD with 2 and 4 flavours of staggered fermions at zero and finite temperature T. We find that chi presents a sharp drop across the deconfinement transition. We also study the dependence of chi on the quark mass at T = 0: we have no conclusive evidence for the expected chiral behaviour.

Abstract
We present a study of the topological susceptibility chi on the lattice for full QCD with 2 and 4 flavours of staggered fermions at zero and finite temperature T. We find that chi presents a sharp drop across the deconfinement transition. We also study the dependence of chi on the quark mass at T = 0: we have no conclusive evidence for the expected chiral behaviour.
