We present the measurement of the absolute branching fractions of B+ -> Xc (c) over barK+ and B+ -> (D) over bar ((*)0)pi(+) decays, using a data sample of 772 x 10(6) B (B) over bar pairs collected at the gamma(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. Here, X-c (c) over bar denotes eta(c), J/psi, chi(c0), chi(c1), eta(c) (2S), psi(2S), psi(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+) X(3915)K+) X(3872)K+) to date and the first limit for B(B+ -> X(3915)K+). The measured branching fractions for eta(c) and eta(c)(2S) are the most precise to date, B(B+ -> eta K-c(+)) = (12.0 +/- 0.8 +/- 0.7) x 10(-4) and B(B+ -> eta(c)(2S)K+) = (4.8 +/- 1.1 +/- 0.3) x 10(-4), where the first and second uncertainties are statistical and systematic, respectively. |
