Description

We discuss how lattice simulations might be used to explore what the topological solution of the UA(1) problem means in full QCD. In a pilot study, we measure the topological susceptibility (in physical units) on quenched and unquenched configurations at fixed gauge coupling. The comparison indicates that it is feasible to measure the topological susceptibility in full QCD for various quark masses and temperatures. (orig.)
