Measurement of Branching Fractions and Charge Asymmetries for Exclusive B Decays to Charmonium

摘要

We report measurements of branching fractions and charge asymmetries of exclusive decays of neutral and charged B mesons into two-body final states containing a charmonium state and a light strange meson. The charmonium mesons considered are J/Ψ, Ψ(2S) and X_(c1), and the light meson is either K or K~*. We use a sample of about 124 X 10~6 BB pairs collected with the BABAR detector at the PEP-II storage ring at the Stanford Linear Accelerator Center.
