Full QCD with the Lüscher local bosonic action

We investigate Lüschers method of including dynamical Wilson fermions in a lattice simulation of QCD with two quark flavours. We measure the accuracy of the approximation by comparing it with Hybrid Monte Carlo results for gauge plaquette and Wilson loops. We also introduce an additional global Metropolis step in the update. We show that the complexity of Lüschers algorithm compares favourably with that of the Hybrid Monte Carlo
