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

I review the main theoretical properties and some recent analytical and numerical investigations of the formulations of lattice QCD with chirally twisted Wilson quarks (also known as twisted mass lattice QCD).
The maximally twisted lattice QCD action of an SUf(2) doublet of mass degenerate Wilson quarks gives raise to a real positive fermion determinant and it is invariant under the product of standard parity times the change of sign of the coefficient of the Wilson term. The existence of this spurionic s
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.
