Non-perturbative running and renormalization of kaon four-quark operators with nf=2+1 domain-wall fermions
P. A. Boyle, N. Garron, A. T. Lytle
We compute the renormalization factors of four-quark operators needed for the study of decay in the channel. We evaluate the Z-factors at a low energy scale ($μ_0…
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 π-mesons with isospin 2. We find Re…
Non-perturbative renormalization for general improved staggered bilinears
Andrew T. Lytle, Stephen R. Sharpe
We present results for non-perturbative renormalization (NPR) factors for staggered fermion bilinears of arbitrary spin and taste. We use "covariant" bilinears which transform irre…
Opening the Rome-Southampton window for operator mixing matrices
R. Arthur, P. A. Boyle, N. Garron +2
We show that the running of operators which mix under renormalization can be computed fully non-perturbatively as a product of continuum step scaling matrices. These step scaling m…
