Searches for B-(s)(0) -> J/psi p(p)over-bar and B+ -> J/psi p(p)over-bar pi(+) decays

Searches for B-(s)(0) -> J/psi p(p)over-bar and B+ -> J/psi p(p)over-bar pi(+) decays

The results of searches for Bs0 → J/ψ ppmacr; and B + → J/ψ pp̄ π+ decays are reported. The analysis is based on a data sample, corresponding to an integrated luminosity of 1.0 fb-1 of pp collisions, collected with the LHCb detector. An excess with 2.8 σ significance is seen for the decay B s0 → J/ψ...
