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

TL;DR

This paper reports precise measurements of how often B mesons decay into specific charmonium and strange meson states, and examines charge asymmetries, providing insights into CP violation and decay dynamics.

Contribution

It presents new measurements of branching fractions and charge asymmetries for B meson decays involving charmonium states using a large data sample from the BABAR detector.

Findings

Measured branching fractions for B decays to charmonium and K/K* final states.

Determined charge asymmetries in these decay modes.

Provided data to test CP violation and decay models.

Abstract

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/Psi, Psi(2S) and Chi_c1, and the light meson is either K or K*. We use a sample of about 124 million BBbar events collected with the BABAR detector at the PEP-II storage ring at the Stanford Linear Accelerator Center.
