3 / 2 kaon weak matrix elements with non - zero total momentum
نویسنده
چکیده
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 ReA2 with previous results calculated by several methods, and experiment. We also show the I = 2 ππ scattering phase shift.

We calculate ∆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 the Lellouch and Lüscher formula and its extention for non-zero total momentum to extract the infinite volume, center-of-mass frame decay amplitudes. The decay amplitudes obtained from the methods correspond to those from t...
متن کاملKaon Weak Matrix Elements in 2+1 flavor DWF QCD
K → π and K → 0 weak matrix elements of ∆S = 1 operators have been measured in 2+1 flavor domain wall fermion (DWF) QCD on (3 fm)3 lattices with a−1 = 1.73(3) GeV. As is well known, using these matrix elements and chiral perturbation theory allows a determination of the K → ππ matrix elements that enter in the quantitative value for the ∆I = 1/2 rule and ε ′/ε . Two light dynamical sea quark ma...
متن کاملPerturbative QCD Effects in Heavy Meson Decays
The amplitude for the exclusive nonleptonic decay of a heavy meson into two light pseudoscalar mesons is analyzed using the factorization formalism of perturbative QCD for exclusive reactions at large momentum transfer. We show that the leading contribution to such amplitudes is proportional to (rs(Q2) where Q” scales with the heavy meson mass squared. Branching ratios for a few B” decay modes ...

The techniques of lattice gauge theory offer the possibility of accurate, non-perturbative calculation of the masses and matrix elements predicted by low-energy QCD. Of particular interest are the properties of the K-meson system and the lowenergy, weak matrix elements that are required to understand Kaon decays, especially those which enter the K → ππ amplitudes which violate CP symmetry.
