- W2600380044 abstract "We present a lattice quantum chromodynamics determination of the scalar and vector form factors for the ${B}_{s}ensuremath{rightarrow}{D}_{s}ensuremath{ell}ensuremath{nu}$ decay over the full physical range of momentum transfer. In conjunction with future experimental data, our results will provide a new method to extract $|{V}_{cb}|$, which may elucidate the current tension between exclusive and inclusive determinations of this parameter. Combining the form factor results at nonzero recoil with recent HPQCD results for the $Bensuremath{rightarrow}Densuremath{ell}ensuremath{nu}$ form factors, we determine the ratios ${f}_{0}^{{B}_{s}ensuremath{rightarrow}{D}_{s}}({M}_{ensuremath{pi}}^{2})/{f}_{0}^{Bensuremath{rightarrow}D}({M}_{K}^{2})=1.000(62)$ and ${f}_{0}^{{B}_{s}ensuremath{rightarrow}{D}_{s}}({M}_{ensuremath{pi}}^{2})/{f}_{0}^{Bensuremath{rightarrow}D}({M}_{ensuremath{pi}}^{2})=1.006(62)$. These results give the fragmentation fraction ratios ${f}_{s}/{f}_{d}=0.310(30{)}_{text{stat}}(21{)}_{text{syst}}(6{)}_{text{theor}}(38{)}_{text{latt}}$ and ${f}_{s}/{f}_{d}=phantom{rule{0ex}{0ex}}0.307(16{)}_{text{stat}}(21{)}_{text{syst}}(23{)}_{text{theor}}(44{)}_{text{latt}}$, respectively. The fragmentation fraction ratio is an important ingredient in experimental determinations of ${B}_{s}$ meson branching fractions at hadron colliders, in particular for the rare decay $mathcal{B}({B}_{s}ensuremath{rightarrow}{ensuremath{mu}}^{+}{ensuremath{mu}}^{ensuremath{-}})$. In addition to the form factor results, we make the first prediction of the branching fraction ratio $R({D}_{s})=mathcal{B}({B}_{s}ensuremath{rightarrow}{D}_{s}ensuremath{tau}ensuremath{nu})/mathcal{B}({B}_{s}ensuremath{rightarrow}{D}_{s}ensuremath{ell}ensuremath{nu})=0.301(6)$, where $ensuremath{ell}$ is an electron or muon. Current experimental measurements of the corresponding ratio for the semileptonic decays of $B$ mesons disagree with Standard Model expectations at the level of nearly four standard deviations. Future experimental measurements of $R({D}_{s})$ may help understand this discrepancy." @default.
