Determination of f_s/f_d for 7 TeV pp collisions and a measurement of the branching fraction of the decay Bd->D-K+

LHCb Collaboration, R. Aaij, B. Adeva +548

The relative abundance of the three decay modes $B_d\to D^{-}{K}^{+}$, $B_d\to D^{-}{\pi }^{+}$ and $B_s\to D_s^{-}{\pi }^{+}$ produced in 7 TeV $pp$ collisions at the LHC is determined from data co…
