Observation of $B_s^0\to K^{\ast \pm }{K}^{\mp }$ and evidence for $B_s^0\to K^{\ast -}{\pi }^{+}$ decays

LHCb collaboration, R. Aaij, B. Adeva +700

Measurements of the branching fractions of $B_s^0\to K^{\ast \pm }{K}^{\mp }$ and $B_s^0\to K^{\ast \pm }{\pi }^{\mp }$ decays are performed using a data sample corresponding to $1.0{\mathrm{fb}}^{-1}$ o…
