NON-HERMITIAN EXACT LOCAL BOSONIC ALGORITHM FOR DYNAMICAL QUARKS

We present an exact version of the local bosonic algorithm for the sim ulation of dynamical quarks in lattice QCD. This version is based on a non-hermitian polynomial approximation of the inverse of the quark ma trix. A Metropolis test corrects the systematic errors. Two variants o f this test are presented. For both of them, a formal proof is given t hat this Monte Carlo algorithm converges to the right distribution. Si mulation data are presented for different lattice parameters. The dyna mics of the algorithm and its scaling in lattice volume and quark mass are investigated.
