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.
