Results on B to Charmonia Decays from CLEO

TL;DR

This paper reviews recent experimental results from CLEO on B meson decays to charmonia, including branching fractions, CP violation searches, and production studies, based on a dataset of 9.7 million BBbar pairs.

Contribution

It provides updated measurements and searches related to B to charmonia decays, enhancing understanding of B meson decay mechanisms and CP violation.

Findings

Measured branching fractions for B^0 to J/Ψ K^0_s, χ_{c1} K^0_s, and J/Ψ π^0.

Searched for direct CP violation in B^{\pm} decays to J/Ψ K^\pm and Ψ(2S) K^\pm.

Observed B to η_c K and studied χ_{c1}, χ_{c2} production and B meson pair production ratios.

Abstract

We review some recent results on B to charmonia decays from CLEO based on 9.7 BBbar pairs collected with the CLEO detector. These include measurements of B^{0} to J\Psi K^0_s, \chi_{c1} K^0_s and J/\Psi \pi^0 branching fractions, search for direct CP violation in B^{\pm} to J/\Psi K^\pm and \Psi(2S) K^\pm, observation of B \to \eta_{c} K, study of \chi_{c1}, \chi_{c2} production and measurement of the relative branching fraction of \Upsilon(4S) to charged and neutral B meson pairs.
