Abstract: | We present the measurement of the absolute branching fractions of B+?Xcc?K+ and B+?D?(?)0?+ decays, using a data sample of 772�106 BB? pairs collected at the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. Here, Xcc? denotes ?c, J/?, ?c0, ?c1, ?c(2S), ?(2S), ?(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+)<2.6�10-4 and B(B+?X(3915)K+)<2.8�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 ?c and ?c(2S) are the most precise to date, B(B+??cK+)=(12.0�0.8�0.7)�10-4 and B(B+??c(2S)K+)=(4.8�1.1�0.3)�10-4, where the first and second uncertainties are statistical and systematic, respectively. � 2018 authors.
