description | Recent beauty baryon physics results from the CMS collaboration, obtained using the proton-proton collision data collected at $\sqrt{s}=13$\,TeV, are discussed. Observation of the $\Lambda^0_{\mathrm{b}}\to\mathrm{J}/\psi\Lambda\phi$ decay and measurement of its branching fraction, relative to the $\Lambda^0_{\mathrm{b}}\to\psi\mathrm{(2S)}\Lambda$ decay, is reported. The excited baryon states $\Lambda_{\mathrm{b}}(5912)^0$, $\Lambda_{\mathrm{b}}(5920)^0$, $\Lambda_{\mathrm{b}}(6146)^0$, and $\Lambda_{\mathrm{b}}(6152)^0$ are confirmed and their masses are measured. Observation of a new excited beauty strange baryon, labeled as $\Xi_\mathrm{b}(6100)^{*-}$, is presented. |

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 $Λ_b(5912)^0, Λ_b(5920)^0 , Λ_b(6146)^0$, and $Λ_b(6152)^0$ are confirmed and their masses are measured.
