Abstract: (APS)
In the lattice computation of the topological susceptibility χ of the QCD vacuum, a mixing with the action density operator (g24π2)FμνaFμνa appears. In this paper we give a detailed calculation of this effect at one-loop order for infinite- as well as finite-size lattices.- gauge field theory: SU(N)
