Phenomenology of semileptonic B-meson decays with form factors from lattice QCD
Daping Du, A. X. El-Khadra, Steven Gottlieb +5
We study the exclusive semileptonic -meson decays , , and , computing observables in the Standard model using the recent lattice…
form factors for new-physics searches from lattice QCD
Jon A. Bailey, A. Bazavov, C. Bernard +22
The rare decay arises from flavor-changing neutral currents and could be sensitive to physics beyond the Standard Model. Here, we present the first $ab…
Determination of from a lattice-QCD calculation of the semileptonic form factor with physical quark masses
A. Bazavov, C. Bernard, C. Bouchard +21
We calculate the kaon semileptonic form factor from lattice QCD, working, for the first time, at the physical light-quark masses. We use gauge configurations generated by…
Leptonic decay-constant ratio f_{K^+}/f_{pi^+} from lattice QCD with physical light quarks
A. Bazavov, C. Bernard, C. DeTar +15
A calculation of the ratio of leptonic decay constants f_{K^+}/f_{π^+} makes possible a precise determination of the ratio of CKM matrix elements |V_{us}|/|V_{ud}| in the Standard…
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…
