Studies of B decays to Charmonium at BABAR

TL;DR

This paper reports measurements of B meson decays into various charmonium states using data from the BABAR detector, including inclusive and exclusive branching fractions, and a preliminary study of a specific decay mode.

Contribution

It provides new measurements of B decays to charmonium states and explores the B --> eta_c K decay mode for the first time.

Findings

Measured inclusive branching fractions for J/psi, psi(2S), and Chi_c in B decays.

Reconstructed B decays with specific charmonium states and kaons to determine exclusive branching fractions.

Presented preliminary results for the B --> eta_c K decay mode.

Abstract

Using 22.7 million BBbar events recorded with the BABAR detector, the inclusive branching fractions for the production of J/psi, psi(2S) and Chi_c in B decays are presented. Combining the charmonium state with a K+-, K0, K*+-, K*0 or neutral pion, B decays are reconstructed exlusively and branching fractions are determined. A preliminary study is also presented fot the B --> eta_c K decay mode.
