Neutral B mixing from 2+1 flavor lattice QCD
E. D. Freeland, C. M. Bouchard, C. Bernard +5
We present an update of the Fermilab-MILC Collaboration's calculation of hadronic matrix elements for B^0-\bar{B^0} mixing. This work is a more extended analysis than our recent pu…
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…
Form factors for B and B_s semileptonic decays with NRQCD/HISQ quarks
C. M. Bouchard, G. Peter Lepage, Chris J. Monahan +2
We discuss preliminaries of a calculation of the form factors for the semileptonic decays B -> pi lv, B_s -> K lv, and B -> K ll. We simulate with NRQCD heavy and HISQ light valenc…
B^0_s and B^0 Mixing in the Standard Model and Beyond: A Progress Report
C. Bouchard, A. X. El-Khadra, E. D. Freeland +2
We give a progress report on the calculation of B meson mixing matrix elements, focusing on contributions that could arise beyond the Standard Model. The calculation uses asqtad (l…
Semileptonic decays of K and D mesons in 2+1 flavor QCD
Jon A. Bailey, A. Bazavov, C. Bernard +17
The experimentally measured rates of the semileptonic decays K -> pi l nu and D -> K(pi) l nu can be combined with lattice calculations of the associated form factors to precisely…
B -> D* l nu at zero recoil: an update
Jon A. Bailey, A. Bazavov, C. Bernard +17
We present an update of our calculation of the form factor for B -> D* l nu at zero recoil, with higher statistics and finer lattices. As before, we use the Fermilab action for b a…
