1 99 8 Lattice approach to the ∆ I = 1 / 2 rule 1

Abstract

We discuss a number of old and new methods for computing K → ππ amplitudes on the lattice. They all involve a non-perturbative determination of matching coefficients. We show how problems related to operator mixing can be greatly reduced by using point-split hadronic currents.
