Progress in $K\to \pi \pi$ Decays

Abstract

Recent work by J.~Prades and myself on $K\to \pi \pi$ is described. The first part describes our method to connect in a systematic fashion the short-distance evolution with long-distance matrix-element calculations taking the scheme dependence of the short-distance evolution into account correctly. In the second part I show the results we obtain for the $\Delta I=1/2$ rule in the chiral limit.
