Pseudoscalar decay constants, light-quark masses, and B_K from mixed-action lattice QCD
Jack Laiho, Ruth S. Van de Water
We present updated results for the leptonic decay constants f_pi and f_K, the light u, d, and s-quark masses, and the neutral kaon mixing parameter B_K from mixed-action lattice si…
B and D meson decay constants from 2+1 flavor improved staggered simulations
E. T. Neil, Jon A. Bailey, A. Bazavov +21
We give an update on simulation results for the decay constants f_B, f_{B_s}, f_D and f_{D_s}. These decay constants are important for precision tests of the standard model, in par…
B- and D-meson decay constants from three-flavor lattice QCD
A. Bazavov, C. Bernard, C. M. Bouchard +20
We calculate the leptonic decay constants of B_{(s)} and D_{(s)} mesons in lattice QCD using staggered light quarks and Fermilab bottom and charm quarks. We compute the heavy-light…
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…
B Mixing in the Standard Model and Beyond: Lattice QCD
C. Bernard, C. M. Bouchard, A. X. El-Khadra +5
We give a brief overview and progress report on our lattice QCD calculation of neutral B mixing hadronic matrix elements needed for Standard Model and Beyond the Standard Model phy…
Semileptonic B to D decays at nonzero recoil with 2+1 flavors of improved staggered quarks
Si-Wei Qiu, Carleton DeTar, Daping Du +3
The Fermilab Lattice-MILC collaboration is completing a comprehensive program of heavy-light physics on the MILC (2+1)-flavor asqtad ensembles with lattice spacings as small as 0.0…
