Abstract

The results of search for new decays of beauty baryons in the LHCb experiment are presented. In particular the new decays Λ b 0 →ψ(2S), \({\rm{\Lambda }}_b^0 \to {\rm{\Lambda }}_c^ + p\overline p {\pi ^ - }\), Λ b 0 pKπ+π, Λ b 0 pKK+K, Ξ b 0 pKπ+π, Ξ b 0 pKπ+K are observed and ratios of branching fractions are measured. The results are based on the proton-proton collisions data collected by the LHCb experiment at the Large Hadron Collider.
