Measurement of the $B_s^0\to D_s^{(\ast )+}{D}_s^{(\ast )-}$ branching fractions

LHCb collaboration, R. Aaij, C. Abellán Beteta +730

The branching fraction of the decay $B_s^0\to D_s^{(\ast )+}{D}_s^{(\ast )-}$ is measured using $pp$ collision data corresponding to an integrated luminosity of $1.0f{b}^{-1}$…
