$B$ meson decays to charmonia at CLEO

We present the recent CLEO results on B meson decays to charmonia. New measurements of the $B0$ decay modes useful for sin 2β measurement are presented. We describe a search for direct CP violation in $B±→J/ψK±$ and $B±→ψ(2S)K±$ decays. First observations of the $B→J/ψφK$ and $B→ηcK$ decays are reported. We present a new measurement of the ratio of charged to neutral B meson production at the Υ(4S). Finally, we describe a precise measurement of the $B0$ and $B+$ meson masses from $B→ψ(′)K$ decays.
