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…
Kaon semileptonic vector form factor and determination of |V_{us}| using staggered fermions
A. Bazavov, C. Bernard, C. M. Bouchard +21
Using staggered fermions and twisted boundary conditions, we calculate the K meson semileptonic decay vector form factor at zero momentum transfer. The HISQ formulation is used for…
Kaon semileptonic decay form factors with HISQ valence quarks
E. Gamiz, J. A. Bailey, A. Bazavov +22
We report on the status of our kaon semileptonic form factor calculations using the highly-improved staggered quark (HISQ) formulation to simulate the valence fermions. We present…
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…
Status of the MILC calculation of electromagnetic contributions to pseudoscalar masses
S. Basak, A. Bazavov, C. Bernard +16
We calculate pseudoscalar masses on gauge configurations containing the effects of 2+1 flavors of dynamical asqtad quarks and quenched electromagnetism. The lattice spacings vary f…
Refining new-physics searches in B -> D tau nu decay with lattice QCD
Jon A. Bailey, A. Bazavov, C. Bernard +23
The semileptonic decay channel B -> D tau nu is sensitive to the presence of a scalar current, such as that mediated by a charged-Higgs boson. Recently the BaBar experiment reporte…
