Abstract

We present the measurement of the absolute branching fractions of B+→Xcc&#175;K+ and B+→D&#175;(*)0π+ decays, using a data sample of 772&#215;106 BB&#175; pairs collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider. Here, Xcc&#175; denotes ηc, J/ψ, χc0, χc1, ηc(2S), ψ(2S), ψ(3770), X(3872), and X(3915). We do not observe significant signals for X(3872) or X(3915) and set the 90% confidence level upper limits at B(B+→X(3872)K+)&lt;2.6&#215;10−4 and B(B+→X(3915)K+)&lt;2.8&#215;10−4. These represent the most stringent upper limit for B(B+→X(3872)K+) to date and the first limit for B(B+→X(3915)K+). The measured branching fractions for ηc and ηc(2S) are the most precise to date, B(B+→ηcK+)=(12.0&#177;0.8&#177;0.7)&#215;10−4 and B(B+→ηc(2S)K+)=(4.8&#177;1.1&#177;0.3)&#215;10−4, where the first and second uncertainties are statistical and systematic, respectively.
