Abstract

The branching fractions of the decay B<sup>+</sup> → pp̄K<sup>+</sup> for different intermediate states are measured using data, corresponding to an integrated luminosity of 1.0 fb<sup>-1</sup>, collected by the LHCb experiment. The total branching fraction, its charmless component M<sub>pp̄</sub> < 2.85 GeV/c<sup>2</sup> and the branching fractions via the resonant cc̄ states η <sub>c</sub>(1S) and ψ(2S) relative to the decay via a J/ψ intermediate state are [Equation not available: see fulltext.] Upper limits on the B <sup>+</sup> branching fractions into the η <sub>c</sub>(2S) meson and into the charmonium-like states X(3872) and X(3915) are also obtained.
