| Abstract | Despite recent progress with other fermion formulations, lattice QCD with Wilson type quarks remains attractive because it is computationally cheap and does not suffer from mixing between flavour and spin degrees of freedom (unlike staggered fermions). On the other hand, all axial symmetries are explicitly broken, which leads to mixing of operators with opposite chirality, and the possible occurence of unphysical fermion zero modes in the quenched approximation. In order to avoid the latter problem in typical quenched simulations, the masses of pseudoscalar mesons are typically heavier than the physical kaon mass. Concerning the |
