  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.
