J. Phys.: Conf. Ser. J. Phys.: Conf. Ser. 1742-6596 Studies of excited states of beauty hadrons at CMS Ivanov Kirill Moscow, MIPT 2020 1690 Studies of excited states of beauty mesons and baryons, performed at the CMS Experiment, are presented. The first observation of $B\tfrac{+}{c}$ (2S) and  $B\tfrac{*+}{c}$ (2S) states in the  $B\tfrac{+}{c}{\pi }^{+}{\pi }^{-}$ invariant mass spectrum is reported as well as the study of excited Λb(5912)0, Λb(5920)0, Λb(6146)0 and Λb(6152)0 baryons decaying to  ${\Lambda }\tfrac{0}{b}{\pi }^{+}{\pi }^{-}$.The analyses use Run-2 data collected in pp collisions at  $\sqrt{s}$ = 13 TeV. research-article
