Calcutation of kaon matrix elements in quenched domain-wall QCD with DBW2 gauge action

Abstract

We give a progress report of our new $a^{-1}\approx 3$ GeV quenched calculation of kaon matrix elements with domain-wall fermion and DBW2 gauge action. Our smaller lattice spacing allows us to address the effect of charmed quark on the lattice. We show preliminary results of $B_K$ renormalized non-perturbatively and $K\to \pi$ matrix elements.
