Quantum Chromodynamics on a lattice with Wilson fermions and a chirallytwisted mass term is considered in the framework of chiral perturbation theory.For two and three numbers of quark flavours, respectively, with non-degeneratequark masses the pseudoscalar meson masses and decay constants are calculatedin next-to-leading order including lattice effects quadratic in the latticespacing a.Comment: 9 pages, LaTeX2e, reference adde
