Search for B --> chi_c K(*) decays

TL;DR

This paper reports a search for specific suppressed B meson decays into chi_c states and kaons, using a large dataset, but finds no significant signals and sets upper limits on their branching fractions.

Contribution

First search for B -> chi_c0 K(*) and B -> chi_c2 K(*) decays with experimental data, providing upper bounds on their branching fractions.

Findings

No significant signals detected.

Upper bounds established for branching fractions.

Results are preliminary.

Abstract

We report on the search for the factorization suppressed decays B -> chi_c0 K(*) and B -> chi_c2 K(*), with chi_c0 and chi_c2 decaying into J/psi gamma. We use a sample of 124 million BBbar events collected with the BABAR detector at the PEP-II storage ring at the Stanford Linear Accelerator Center. No significant signal is found and upper bounds for the branching fractions are obtained. All results are preliminary.
