Abstract :
By using suitable Ward identities, we show that it is possible to compute K0–K̄0 mixing without subtracting the terms generated by explicit chiral symmetry breaking present in Wilson-like lattice actions. The accuracy in the determination of the amplitudes is of O(a), which is the best one attainable in the absence of improvement.
