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…
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…
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…
Delta I=3/2 K to pi-pi decays with nearly physical kinematics
Elaine Goode, Matthew Lightman
The ΔI = 3/2 K to pi pi decay amplitude is calculated on RBC/UKQCD 32^3 times 64, L_s=32 dynamical lattices with 2+1 flavours of domain wall fermions using the Dislocation Suppress…
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 π-mesons with isospin 2. We find Re…
