Chiral perturbation theory for partially quenched twisted mass lattice QCD

G Münster, C Schmidt, E Scholz
2004 Europhysics letters  
Partially quenched Quantum Chromodynamics with Wilson fermions on a lattice is considered in the framework of chiral perturbation theory. Two degenerate quark flavours are associated with a chirally twisted mass term. The pion masses and decay constants are calculated in next-to-leading order including terms linear in the lattice spacing a.
