  Expansions of the Wilson determinant in lattice QCD with quarks produce gauge
action terms which shift the coupling constant of the fundamental
representation plaquette action and induce an adjoint representation plaquette
action. We study the magnitude of these induced couplings with two flavors of
Wilson fermions. We utilize a microcanonical demon method, which allows us to
measure the induced couplings directly from gauge configurations generated by
full fermionic simulations.
