摘要：We discuss how the peculiar properties of maximally twistedWilson fermions can be exploited to
set up a consistent LQCD computational scheme in which the CP-conserving matrix elements of
the DS = 1;2 effective weak Hamiltonian can be evaluated without mixing with wrong-chirality
and/or -parity operators. The proposed lattice framework guarantees automatic O(a) improvement
and positive determinant also for pairs of non-degenerate quarks.
