Description

The topological susceptibility χ is computed in SU(2) lattice gauge theory including dynamical Wilson fermions in lowest order hopping parameter expansion. At a finite temperature corresponding to the confining phase we observe a decreasing value of χ (in units of the lattice spacing) with increasing hopping parameter. (orig.)
