Abstract

An overview is given on the first observation of the B⁺→Χ_c0K⁺. The statistical significance of the signal is 6σ when the Χ_c0→π⁺π^- and Χ_c0→K*Kπ modes are combined. The measured branching fraction is Β(Β→Χ_c0K⁺) = (6.0_-1.8^+2.1 ± 1.1) × 10^-4 which is comparable to those for the B⁺ → J/ψK⁺ and B⁺ → Χ_c1K⁺ decays. This provides evidence for a significant nonfactorizable contribution in B to charmonium decay processes.
