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…
Semileptonic B to D decays at nonzero recoil with 2+1 flavors of improved staggered quarks. An update
Si-Wei Qiu, Carleton DeTar, Daping Du +3
The Fermilab Lattice and MILC collaborations are completing a comprehensive program of heavy-light physics on MILC (2+1)-flavor asqtad ensembles with lattice spacings as small as 0…
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…
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…
B_s->D_s/B->D Semileptonic Form-Factor Ratios and Their Application to BR(B^0_s->μ^+μ^-)
Jon A. Bailey, A. Bazavov, C. Bernard +23
We calculate form-factor ratios between the semileptonic decays \bar{B}->D^+\ell^-\barν and \bar{B}_s->D_s^+\ell^-\barν with lattice QCD. These ratios are a key theoretical input i…
