| Abstract | 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. |
