Contribution
It provides new experimental measurements of branching fractions, decay amplitudes, and B meson masses for specific charmonium final states in B decays.
Findings
Branching fractions for B decays to charmonium states are measured.
Decay amplitudes for B0 --> J/psi K* are determined.
B0 and B+ meson masses are measured.
Abstract
We report on exclusive decays of B mesons into final states containing charmonium using data collected with the BABAR detector at the PEP-II storage rings. The charmonium states considered here are J/psi, psi(2S), and chi_C1. Branching fractions for several exclusive final states, a measurement of the decay amplitudes for the B0 --> J/psi K* decay, and measurements of the B0 and B+ masses are presented. All of the results we present here are preliminary.
