- and -meson leptonic decay constants from four-flavor lattice QCD
A. Bazavov, C. Bernard, N. Brown +14
We calculate the leptonic decay constants of heavy-light pseudoscalar mesons with charm and bottom quarks in lattice quantum chromodynamics on four-flavor QCD gauge-field configura…
form factors with 2+1 flavors
Fermilab Lattice, MILC Collaborations, : +23
Using the MILC 2+1 flavor asqtad quark action ensembles, we are calculating the form factors and for the semileptonic decay. A total of six en…
Semileptonic -meson decays to light pseudoscalar mesons on the HISQ ensembles
Zechariah Gelzer, C. Bernard, C. DeTar +10
We report the status of an ongoing lattice-QCD calculation of form factors for exclusive semileptonic decays of mesons with both charged currents (, …
Strong-isospin-breaking correction to the muon anomalous magnetic moment from lattice QCD at the physical point
Bipasha Chakraborty, C. T. H. Davies, C. DeTar +17
All lattice-QCD calculations of the hadronic-vacuum-polarization contribution to the muon's anomalous magnetic moment to-date have been performed with degenerate up- and down-quark…
Short-distance matrix elements for -meson mixing for lattice QCD
A. Bazavov, C. Bernard, C. M. Bouchard +17
We calculate in three-flavor lattice QCD the short-distance hadronic matrix elements of all five four-fermion operators that contribute to neutral -meson mixing both in a…
D-Meson Mixing in 2+1-Flavor Lattice QCD
Chia Cheng Chang, C. M. Bouchard, A. X. El-Khadra +7
We present results for neutral D-meson mixing in 2+1-flavor lattice QCD. We compute the matrix elements for all five operators that contribute to D mixing at short distances, inclu…
