Chiral perturbation theory for twisted mass QCD
arXiv:hep-lat/0409066 · doi:10.1016/j.nuclphysbps.2004.11.117
Abstract
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 masses and decay constants are calculated in next-to-leading order including terms linear in the lattice spacing a. We treat both unquenched and partially quenched QCD. We also discuss the phase structure of twisted mass lattice QCD.
