The Decay Amplitude from Lattice QCD
T. Blum, P. A. Boyle, N. H. Christ +13
We report on the first realistic \emph{ab initio} calculation of a hadronic weak decay, that of the amplitude for a kaon to decay into two Ï-mesons with isospin 2. We find R…

Lattice determination of the Decay Amplitude
T. Blum, P. A. Boyle, N. H. Christ +13
We describe the computation of the amplitude A_2 for a kaon to decay into two pions with isospin I=2. The results presented in the letter Phys.Rev.Lett. 108 (2012) 141601 from an a…

to Decay amplitudes from Lattice QCD
T. Blum, P. A. Boyle, N. H. Christ +11
We report a direct lattice calculation of the to decay matrix elements for both the and 3/2 amplitudes and on 2+1 flavor, domain wall fermion, $16^…
