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

✦ Synopsis
The O(a') contributions to the chiral effective Lagrangian for lattice QCD with Wilson fermions are constructed. The results a.re generalized to partially quenched QCD with Wilson fermions as well as to the "mixed" lattice theory with Wilson sea quarks a.nd Ginsparg-Wilson valence quarks.

I present a selection of recent lattice data by major collaborations for the pseudo-Goldstone boson masses in full (N f = 2) QCD, where the valence quarks are chosen exactly degenerate with the sea quarks. At least the more chiral points should be consistent with Chiral Perturbation Theory for the l
