Progress in $K\to\pi\pi$ Decays
Johan Bijnens
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.
