Résumé

A search for the decays of the B⁺ _c meson to pp-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, fcfu×B(B⁺ _c→ppπ⁺)<3.6×10-8 in the kinematic region m(pp)<2.85 GeV/c2, 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 B_c+ (B⁺) meson.
