2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/36832We 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.18 pages, 7 postscript figures, contributed paper to ICHEP2000High Energy Physics - Experimenttext
