Description
The study of excited $\Lambda_{\mathrm{b}}^0$ baryons is reported, based on a data sample of $140$\,fb$^{-1}$ collected with the CMS detector in proton-proton collision at centre-of-mass energy of 13 TeV. Existence of four baryon states $\Lambda_{\mathrm{b}}^*(5912)^0$, $\Lambda_{\mathrm{b}}^*(5920)^0$, $\Lambda_{\mathrm{b}}^*(6146)^0$, and $\Lambda_{\mathrm{b}}^*(6152)^0$ is confirmed and their masses are measured.
