摘要：We present preliminary results for the DI = 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 ReA2 with previous results calculated by several methods, and experiment. We also show the
I = 2 pp scattering phase shift.
