A note on momentum subtraction schemes for quark bilinears and semileptonic operators

P. A. Boyle, M. Bruno, M. Gorbahn +4

In this work we examine a family of regularization invariant (RI) symmetric momentum (SMOM) schemes for semi-leptonic operators. By working with chirally symmetric and massless QCD…

An exploratory calculation of $K_{L} \to I^¼^{+} I^¼^{-}$ decay from Lattice QCD at physical pion mass

Peter Boyle, En-Hung Chao, Norman Christ +3

We compute the complex, long-distance two-photon-exchange amplitude which contributes to the rare $K_{L} \to I^¼^{+} I^¼^{-}$ decay from lattice QCD. We use a $2 4^{3} \times 64$ ph…

The long-distance window of the hadronic vacuum polarization for the muon g-2

T. Blum, P. A. Boyle, M. Bruno +15

We provide the first ab-initio calculation of the Euclidean long-distance window of the isospin symmetric light-quark connected contribution to the hadronic vacuum polarization for…

Multiple right hand side multigrid for domain wall fermions with a multigrid preconditioned block conjugate gradient algorithm

Peter A Boyle

We introduce a class of efficient multiple right-hand side multigrid algorithm for domain wall fermions. The simultaneous solution for a modest number of right hand sides concurren…
