Light Hadron Weak Matrix Elements

Abstract

Recent developments in lattice QCD calculation of weak matrix elements involving light quarks are described. We focus on four topics: $B_K$ with the Kogut-Susskind and Wilson quark actions, $\Delta I=1/2$ rule, proton decay matrix elements and the application of domain wall QCD to calculation of weak matrix elements.
