Abstract
Wilson Fermions with untwisted and twisted mass are widely used in latticesimulations. Therefore one important question is whether the twist angle andthe lattice spacing affect the phase diagram. We briefly report on the study ofthe phase diagram of QCD in the parameter space of the degenerate quark masses,isospin chemical potential, lattice spacing, and twist angle by employingchiral perturbation theory. Moreover we calculate the pion masses and theirdependence on these four parameters.
