LHCb performance on $B_{s}^{0} \to h^{+}h^{-}$ measurements

The selection of B/sup 0/ to pi /sup +/ pi /sup -/, B/sup 0/ to K/sup +/ pi /sup -/, B/sub s//sup 0/ to K/sup +/K/sup -/ and B/sub s//sup 0 / to pi /sup +/K/sup -/ decays at LHCb is presented, and the estimated annual signal yields and background-to-signal ratios for specific and combinatorial backg...

description The selection of B/sup 0/ to pi /sup +/ pi /sup -/, B/sup 0/ to K/sup +/ pi /sup -/, B/sub s//sup 0/ to K/sup +/K/sup -/ and B/sub s//sup 0 / to pi /sup +/K/sup -/ decays at LHCb is presented, and the estimated annual signal yields and background-to-signal ratios for specific and combinatorial backgrounds are quoted. The combined measurement of the B/sup 0/ to pi /sup +/ pi /sup -/ and B/sub s//sup 0/ to K/sup +/K/sup -/ CP asymmetries provides a promising strategy to determine the gamma angle of the unitarity triangle. The results of a study on the sensitivity on the direct and mixing-induced CP- violating observables for B/sup 0/ to pi /sup +/ pi /sup -/ and B/sub s//sup 0/ to K/sup +/K/sup -/decays, as well as on gamma are also discussed.
