##### Abstract

After integration over the fermions in an SU(2) lattice gauge theory, the effective fermionic action may be expressed as a sum over all possible closed gauge field loops with corresponding weight factors. We approximate this sum and perform a Monte Carlo simulation of a coupled fermion-gauge system on a 44 lattice. We compare our results for left angle bracketSeffright-pointing angle bracket and Image for different values of the gauge field coupling β and fermion coupling κ with the free fermion theory on a lattice. left angle bracketSeffright-pointing angle bracket turns out to be quite small for Image.
