A total signal of approximately 900 events was reconstructed, and  the relative branching fractions of each decay mode were  determined with a likelihood fit. We report the first observation of  the decay of a bottom-strange meson into two charged kaons. We measured the direct CP-violating asymmetry in the decay of a  bottom meson into a charged pion and a kaon in agreement with  world average values.  These measurements are performed for the first time in a hadron  collider.  No evidence for other modes was found, and we set upper  limits to the decay rates of rarer modes.
