Abstract

The branching fraction of the decay ${B}_{s}^{0}\ensuremath{\rightarrow}{D}_{s}^{(*)+}{D}_{s}^{(*)\ensuremath{-}}$ is measured using $pp$ collision data corresponding to an integrated luminosity of $1.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, collected using the LHCb detector at a center-of-mass energy of 7 TeV. It is found to be $\mathcal{B}({B}_{s}^{0}\ensuremath{\rightarrow}{D}_{s}^{(*)+}{D}_{s}^{(*)\ensuremath{-}})=(3.05\ifmmode\pm\else\textpm\fi{}0.10\ifmmode\pm\else\textpm\fi{}0.20\ifmmode\pm\else\textpm\fi{}0.34)%$, where the uncertainties are statistical, systematic, and due to the normalization channel, respectively. The branching fractions of the individual decays corresponding to the presence of one or two ${D}_{s}^{*\ifmmode\pm\else\textpm\fi{}}$ are also measured. The individual branching fractions are found to be $\mathcal{B}({B}_{s}^{0}\ensuremath{\rightarrow}{D}_{s}^{*\ifmmode\pm\else\textpm\fi{}}{D}_{s}^{\ensuremath{\mp}})=(1.35\ifmmode\pm\else\textpm\fi{}0.06\ifmmode\pm\else\textpm\fi{}0.09\ifmmode\pm\else\textpm\fi{}0.15)%$, $\mathcal{B}({B}_{s}^{0}\ensuremath{\rightarrow}{D}_{s}^{*+}{D}_{s}^{*\ensuremath{-}})=(1.27\ifmmode\pm\else\textpm\fi{}0.08\ifmmode\pm\else\textpm\fi{}0.10\ifmmode\pm\else\textpm\fi{}0.14)%$. All three results are the most precise determinations to date.
