Branching fraction and properties of B meson decays to charmonium at Belle

Abstract The latest Belle results on B meson decays to charmonium are reported. The topics include the first observation of the η c (2 S ) meson, which is a charmonium state so far missing; an observation of factorization-forbidden decays: B → χ C 2 X and χ C 0 K ; and search for more CP eigenstates in both Cabibbo-favored and Cabibbo-suppressed decays.
