Abstract

Recent beauty baryon physics results from the CMS collaboration, obtained using the proton-proton collision data collected at √ s = 13 TeV, are discussed. Observation of the Λ 0 b → J/ψΛφ decay and measurement of its branching fraction, relative to the Λ 0 b → ψ(2S)Λ decay, is reported. The excited baryon states Λb(5912)0 , Λb(5920)0 , Λb(6146)0 , and Λb(6152)0 are confirmed and their masses are measured. Observation of a new excited beauty strange baryon, labeled as Ξb(6100)∗−, is presented.
