Abstract

We present preliminary results for the ∆I = 3/2 kaon decay matrix elements using domain wall fermions and the DBW2 gauge action at one coarse lattice spacing corresponding to a −1 = 1.3 GeV. We employ an extention of the Lellouch and Lüscher formula for non-zero total momentum to extract the infinite volume, center-of-mass system decay amplitudes. We compare the result of ReA 2 with previous results calculated by several methods, and experiment. We also show the I = 2 ππ scattering phase shift. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence. ∆I = 3/2 kaon weak matrix elements with non-zero total momentum Takeshi Yamazaki
