Search for New Decays of Beauty Baryons in the LHCb Experiment

Аннотация

The results of search for new decays of beauty baryons in the LHCb experiment are presented. In particular the new decays Λ_b⁰→ψ(2S)pπ⁻, \({\rm{\Lambda }}_b^0 \to {\rm{\Lambda }}_c^ + p\overline p {\pi ^ - }\), Λ_b⁰→pK⁻π⁺π⁻, Λ_b⁰→pK⁻K⁺K⁻, Ξ_b⁰ → pK⁻π⁺π⁻, Ξ_b⁰ → pK⁻π⁺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.
