semileptonic form factors from unquenched lattice QCD and determination of
J. A. Bailey, A. Bazavov, C. Bernard +22
We compute the semileptonic form factors and update the determination of the CKM matrix element . We use the MILC asqtad ensembles with sea quarks…
Dynamical QCD+QED simulation with staggered quarks
Ran Zhou, Steven Gottlieb
Electromagnetic effects play an important role in many phenomena such as isospin-symmetry breaking in the hadron spectrum and the hadronic contributions to g-2. We have generalized…
Gradient Flow Analysis on MILC HISQ Ensembles
A. Bazavov, C. Bernard, N. Brown +13
We report on a preliminary scale determination with gradient-flow techniques on the HISQ ensembles generated by the MILC collaboration. The ensembles include four…
Charmed and light pseudoscalar meson decay constants from HISQ simulations
A. Bazavov, C. Bernard, C. Bouchard +20
We compute the leptonic decay constants , , and , and the quark-mass ratios and in unquenched lattice QCD. We use the MILC highly imp…
Staggered Dslash Performance on Intel Xeon Phi Architecture
Ruizi Li, Steven Gottlieb
The conjugate gradient (CG) algorithm is among the most essential and time consuming parts of lattice calculations with staggered quarks. We test the performance of CG and dslash,…
Finite-volume effects and the electromagnetic contributions to kaon and pion masses
S. Basak, A. Bazavov, C. Bernard +14
We report on the MILC Collaboration calculation of electromagnetic effects on light pseudoscalar mesons. The simulations employ asqtad staggered dynamical quarks in QCD plus quench…
