Description

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