The relation between the physical K → ππ matrix elements and K → π matrix elements deduced from chiral perturbation theory is recapitulated. Quenched numerical simulations are performed on an 163 × 32 × 16 lattice at a lattice spacing a?1 ? 2GeV for both the standard plaquette gauge action and a renormalization-group improved gauge action, and reasonable signals for K → π matrix elements are obtained. Preliminary results are reported on the K → ππ matrix elements, and results from two actions are compared.}, title = {Calculation of K→π matrix elements in quenched domain-wall QCD}, year = {2001}, yomi = {イワサキ, ヨウイチ and ウカワ, アキラ} }
