Isospin breaking corrections to a lattice QCD calculation of
Norman H. Christ, Erik Lundstrum
Because of the rule, the effects of electromagnetism and the isospin-breaking light quark mass difference on the direct CP violation parameter may be as l…
from lattice QCD
En-Hung Chao, Norman H. Christ, Xu Feng +1
We propose a lattice-QCD-suitable framework for computing the two-photon long-distance contribution to the complex decay amplitude, where QED is treate…
Long-distance contribution to from lattice QCD
Ziyuan Bai, Norman H. Christ, Joseph M. Karpie +3
A lattice QCD approach to the calculation of the long-distance contributions to is presented. This parameter describes indirect CP violation in decay. While the shor…
Erratum: Standard-model prediction for direct CP violation in decay
Z. Bai, T. Blum, P. A. Boyle +11
In this document we address an error discovered in the ensemble generation for our calculation of the amplitude (Phys. Rev. Lett. 115, 212001 (2015), arXiv:1505.0786…
B-meson decay constants from 2+1-flavor lattice QCD with domain-wall light quarks and relativistic heavy quarks
Norman H. Christ, Jonathan M. Flynn, Taku Izubuchi +5
We calculate the B-meson decay constants f_B, f_Bs, and their ratio in unquenched lattice QCD using domain-wall light quarks and relativistic b-quarks. We use gauge-field ensembles…
Determination of the amplitude of decays
T. Janowski, C. T. Sachrajda, P. A. Boyle +6
We review the status of recent calculations by the RBC-UKQCD collaboration of the complex amplitude , corresponding to the decay of a kaon to a two pion state with total isosp…
