ABSTRACT
A study of excited $\Lambda_\mathrm{b}^0$ baryons is reported, based on a data sample collected in 2016-2018 with the CMS detector at LHC proton-proton collisions center-of-mass energy 13 TeV, corresponding to an integrated luminosity up 140 fb$^{-1}$. The existence four states: $\Lambda_\mathrm{b}$(5912)$^0$, $\Lambda_\mathrm{b}$(5920)$^0$, $\Lambda_\mathrm{b}$(6146)$^0$, and $\Lambda_\mathrm{b}$(6152)$^0$ $\Lambda_\mathrm{b}^0\pi^+\pi^-$ mass spectrum confirmed, their masses are measured. distribution exhibits broad excess events region 6040-6100 MeV, whose origin cannot be discerned present data.
