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…

Semileptonic Kaon Decay in Staggered Chiral Perturbation Theory

C. Bernard, J. Bijnens, E. Gámiz

The determination of $∣ V_{u s} ∣$ from kaon semileptonic decays requires the value of the form factor $f_{+} (q^{2} = 0)$ , which can be calculated precisely on the lattice. We prov…

Determination of $∣ V_{u s} ∣$ from a lattice-QCD calculation of the $K \to π ℓ ν$ semileptonic form factor with physical quark masses

A. Bazavov, C. Bernard, C. Bouchard +21

We calculate the kaon semileptonic form factor $f_{+} (0)$ from lattice QCD, working, for the first time, at the physical light-quark masses. We use gauge configurations generated by…

Charmed and strange pseudoscalar meson decay constants from HISQ simulations

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

We update our determinations of $f_{D^{+}}$ , $f_{D_{s}}$ , $f_{K}$ , and quark mass ratios from simulations with four flavors of HISQ dynamical quarks. The availability of ensembles with l…

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…

|V_us| from hadronic τ decays

Elvira Gámiz

We review the status and future prospects of the determination of the CKM matrix element |V_us| using inclusive strange hadronic τ decay data. We also review the results for |V_us|…
