Non-degenerate light quark masses from 2+1f lattice QCD+QED
TL;DR: In this paper, the effects of isospin breaking in Lattice QCD+QED were investigated using Chiral Perturbation Theory with Electromagnetic corrections to find the renormalized, non-degenerate, light quark masses.
Proceedings ArticleDOI
Prospects for the Calculation of Rare Kaon Decay Amplitudes from Lattice Simulations
TL;DR: In this paper, the authors focus on quantities which have not been previously computed in lattice computations and for which the RBC-UKQCD collaborations are developing the necessary theoretical and computational framework.

Kaon Weak Matrix Elements with Wilson Fermions
Damir Becirevic,Ph. Boucaud,V. Gimenez,C.-J.D. Lin,Vittorio Lubicz,Guido Martinelli,Mauro Papinutto,Christopher T. Sachrajda +7 more
TL;DR: In this paper, the B_K parameter is computed by using two different methods and extrapolate to the continuum limit, and the preliminary result is B_k(2 GeV)=0.66(7).

Electromagnetic Corrections to Meson Masses and the HVP
Peter Boyle,Vera Gülpers,James Harrison,Andreas Jüttner,Antonin Portelli,Christopher T. Sachrajda +5 more
TL;DR: In this article, the electromagnetic corrections to meson masses and the hadronic vacuum polarization using Domain Wall fermions were estimated with two different approaches, a stochastic approach using $U(1)$ gauge configurations for the photon fields, and a perturbative approach through a QED perturbation expansion of the QCD+QED path integral.

Kaon Mixing Beyond the Standard Model
TL;DR: In this article, an ongoing calculation of hadronic matrix elements needed to parameterize K-Kbar mixing in generic BSM scenarios, using domain wall fermions (DWF) at two lattice spacings.
