Evidence for the two-body charmless baryonic decay B+→pΛ¯

A search for the rare two-body charmless baryonic decay B+→pΛ¯$$ {B}^{+}\to p\overline{\varLambda} $$ is performed with pp collision data, corresponding to an integrated luminosity of 3 fb−1, collected by the LHCb experiment at centre-of-mass energies of 7 and 8 TeV. An excess of B+→pΛ¯$$ {B}^{+}\to
