Two-point Correlator Fits on HISQ Ensembles
A. Bazavov, C. Bernard, C. Bouchard +22
We present our methods to fit the two point correlators for light, strange, and charmed pseudoscalar meson physics with the highly improved staggered quark (HISQ) action. We make u…
Properties of light pseudoscalars from lattice QCD with HISQ ensembles
MILC Collaboration, A. Bazavov, C. Bernard +14
We fit lattice-QCD data for light-pseudoscalar masses and decay constants, from HISQ configurations generated by MILC, to SU(3) staggered chiral perturbation theory. At present suc…
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…
Continuum Limit Physics from 2+1 Flavor Domain Wall QCD
Y. Aoki, R. Arthur, T. Blum +23
We present physical results obtained from simulations using 2+1 flavors of domain wall quarks and the Iwasaki gauge action at two values of the lattice spacing , (=\,1.7…
Continuum Limit of from 2+1 Flavor Domain Wall QCD
Y. Aoki, R. Arthur, T. Blum +17
We determine the neutral kaon mixing matrix element in the continuum limit with 2+1 flavors of domain wall fermions, using the Iwasaki gauge action at two different lattice s…
Pseudoscalar meson physics with four dynamical quarks
A. Bazavov, C. Bernard, C. Bouchard +22
We present preliminary results for light, strange and charmed pseudoscalar meson physics from simulations using four flavors of dynamical quarks with the highly improved staggered…
Leptonic decay-constant ratio f_{K^+}/f_{pi^+} from lattice QCD with physical light quarks
A. Bazavov, C. Bernard, C. DeTar +15
A calculation of the ratio of leptonic decay constants f_{K^+}/f_{Ï^+} makes possible a precise determination of the ratio of CKM matrix elements |V_{us}|/|V_{ud}| in the Standard…
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…
