| Abstract | Studies of excited states of beauty mesons and baryons, performed at the CMS experiment, are presented. The first observation of $B_c^+(2S)$ and $B_c^{*+}(2S)$ states in the $B_c^+ \pi^+ \pi^-$ invariant mass spectrum is reported as well as the study of excited $\Lambda_b(5912)^0$, $\Lambda_b(5920)^0$, $\Lambda_b(6146)^0$ and $\Lambda_b(6152)^0$ baryons decaying to $\Lambda_b^0 \pi^+ \pi^-$. The analyses use Run-2 data, collected in pp collisions at $\sqrt s$ =13 TeV. |
