Towards more accurate $B_{(s)} \to π (K)$ and $D_{(s)} \to π (K)$ form factors

Logan Roberts, Chris Bouchard, Olmo Francesconi +1

We present progress on the calculation of scalar, vector, and tensor form factors for the following meson decays: $B \to π$ , $B_{s} \to K$ , $D \to π$ and $D_s\righ…

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…

Decay constants $f_{B}$ and $f_{B_{s}}$ from HISQ simulations

Fermilab Lattice, MILC Collaborations, : +25

We give a progress report on a project aimed at a high-precision calculation of the decay constants $f_{B}$ and $f_{B_{s}}$ from simulations with HISQ heavy and light valence and sea q…

The $B \to D ℓ ν$ form factors at nonzero recoil and $∣ V_{c b} ∣$ from $2 + 1$ -flavor lattice QCD

Fermilab Lattice, MILC Collaborations, : +24

We present the first unquenched lattice-QCD calculation of the hadronic form factors for the exclusive decay $B \to D ℓ ν$ at nonzero recoil. We carr…

Neutral B-meson mixing parameters in and beyond the SM with 2+1 flavor lattice QCD

C. M. Bouchard, E. D. Freeland, C. W. Bernard +6

We report on the status of our calculation of the hadronic matrix elements for neutral $B$ -meson mixing with asqtad sea and valence light quarks and using the Wilson clover action…

Heavy-meson semileptonic decays for the Standard Model and beyond

Yuzhi Liu, Ran Zhou, Jon A. Bailey +25

We calculate the form factors for the semileptonic decays $B_{s} \to K ℓ ν$ and $B \to K ℓℓ$ with lattice QCD. We work at several lattice spacings and a range of light quark mass…

K semileptonic form factor with HISQ fermions at the physical point

E. Gámiz, A. Bazavov, C. Bernard +21

We present results for the form factor $f_{+}^{K π} (0)$ , needed to extract the CKM matrix element $∣ V_{u s} ∣$ from experimental data on semileptonic $K$ decays, on the HISQ $N_f=2+1+1…

Two-point Correlator Fits on HISQ Ensembles

A. Bazavov, C. Bernard, C. Bouchard +22

We present our methods to fit the two point correlators for light, strange, and charmed pseudoscalar meson physics with the highly improved staggered quark (HISQ) action. We make u…

Neutral B-meson mixing from three-flavor lattice QCD: Determination of the SU(3)-breaking ratio ξ

A. Bazavov, C. Bernard, C. M. Bouchard +20

We study SU(3)-breaking effects in the neutral B_d-\bar B_d and B_s-\bar B_s systems with unquenched N_f=2+1 lattice QCD. We calculate the relevant matrix elements on the MILC coll…

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…

Progress on charm semileptonic form factors from 2+1 flavor lattice QCD

Jon A. Bailey, A. Bazavov, C. Bernard +19

Lattice calculations of the form factors for the charm semileptonic decays D to K l nu and D to pi l nu provide inputs to direct determinations of the CKM matrix elements |V(cs)| a…
