Abstract

A search for the decays of the Bc+ meson to p anti-p π+ is performed for the first time using a data sample corresponding to an integrated luminosity of 3.0 fb^−1 collected by the LHCb experiment in pp collisions at centre-of-mass energies of 7 and 8 TeV. No signal is found and an upper limit, at 95% confidence level, is set, f_c/f_u × B(Bc+ → p anti-p π+) < 3.6 × 10^−8 in the kinematic region m(p anti-p) < 2.85 GeV/c^2, p_T(B) < 20 GeV/c and 2.0 < y(B) < 4.5, where B is the branching fraction and f_c (f_u) is the fragmentation fraction of the b quark into a Bc+ (B+) meson.
