TL;DR

This paper measures the relative branching fractions of the $B^{+} o p ar p K^{+}$ decay, including charmonium states, to explore Standard Model and potential new physics insights at LHCb.

Contribution

It provides the first measurements of the ratios of branching fractions for the $B^{+} o p ar p K^{+}$ decay, including charmonium contributions, at LHCb.

Findings

Measured ratios of branching fractions for charmonium and charmless components.

Identified the presence of intermediate resonances in the decay channel.

Provided data relevant for CP violation studies.

Abstract

The study of the $B^{+}\to p \bar p K^{+}$ decay channel at LHCb offers great opportunities to study different aspects of the Standard Model and possibly Beyond Standard Model physics. In particular it can be interesting not only for the possibility to measure CP asymmetry but also to study possible intermediate resonances. The ratios of the branching fractions of the $B^{+}\to p \bar p K^{+}$ decay channel, of the charmless component with $M_{p\bar p} < 2.85\unitm{GeV/}c^{2}$ and of the charmonium contribution $\eta_{c}$ relative to the $J/\psi$ are presented.
