Chiral perturbation theory for lattice QCD with a twisted mass term
Institut für Theoretische Physik, Universität Münster Wilhelm-Klemm-Str. 9, D-48149 Münster, Germany
Accepted: 31 March 2004
Quantum chromodynamics on a lattice with Wilson fermions and a chirally twisted mass term for two degenerate quark flavours is considered in the framework of chiral perturbation theory. The pion mass and decay constant are calculated in next-to-leading order including terms linear in the lattice spacing a.
