| Abstract |
We explore the possibility for an evaluation of non-leptonic ΔS = 1 K decay amplitudes through the calculation of K → π matrix elements using domain-wall QCD. 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 16[3] × 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.
