Non-perturbative renormalization in kaon decays

High Energy Physics - Lattice 2009-10-28 v1

Abstract

We discuss the application of the MPSTV non-perturbative method \cite{NPM} to the operators relevant to kaon decays. This enables us to reappraise the long-standing question of the ΔI=1/2\Delta I=1/2 rule, which involves power-divergent subtractions that cannot be evaluated in perturbation theory. We also study the mixing with dimension-six operators and discuss its implications to the chiral behaviour of the BKB_K parameter.
