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 phase structure of zero temperature twisted mass lattice QCD is investigated. We find strong metastabilities in the plaquette observable when the untwisted quark mass sweeps across zero.

A first step towards solving the A1 = l/2 puzzle consists in a determination of the lowest order coupling constants gs and gz7 in the effective chiral theory. Using twisted mass QCD with an active charm, it can be shown that the renormalization of K -+ 7 matrix elements requires at most the subtract

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

We present first results for diquark masses calculated in Landau gauge on the latticr,. These masses as well as quark and baryon masses have been extracted from the long dist,ancr behavior of the correlation functions. We find that, the ordering of the diquark spectrum with spin 0 and 1 states in c
