Abstract

The branching fractions of the decay B+→pp¯K+ for different intermediate states are measured using data, corresponding to an integrated luminosity of 1.0 fb−1, collected by the LHCb experiment. The total branching fraction, its charmless component (Mpp¯<2.85 GeV/c2) and the branching fractions via the resonant cc¯ states η c (1S) and ψ(2S) relative to the decay via a J/ψ intermediate state are Upper limits on the B + branching fractions into the η c (2S) meson and into the charmonium-like states X(3872) and X(3915) are also obtained.
