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 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
