Search for New Tetraquarks Containing a $\mathbb b$ Quark in the CMS Experiment / Chistov, R N (Lebedev Inst.)
A review of the results obtained in the CMS experiment from searches for new multiquark states is given. Attention is paid primarily to searches for four-quark states (tetraquarks) containing heavy $b$ quarks..

Study of Excited $\Lambda _{b}^{0}$ States in the CMS Experiment / Polikarpov, S (Lebedev Inst.)
Using the data acquired in the CMS experiment at the Large Hadron Collider (LHC) within 2016—2018, beautiful baryons decaying into $\Lambda _{b}^{0}{{\pi }^{ + }}{{\pi }^{ - }}$ are studied. The existence of the ${{\Lambda }_{b}}{{(5912)}^{0}}$, ${{\Lambda }_{b}}{{(5920)}^{0}}$, ${{\Lambda }_{b}}{{(6146)}^{0}}$, and ${{\Lambda }_{b}}{{(6152)}^{0}}$ states is confirmed and their masses are measured..

Spectroscopy of $B^+_c$ Mesons and $\Lambda^0_b$ Baryons in the CMS Experiment / Polikarpov, S M (Lebedev Inst.)
The first observation of two excited states of the $B^{+}_{c}$ is presented together with the measurements of the $B_{c}(2S)^{+}$ mass and the mass difference $M(B_{c}^{\ast+})-M(B_{c}^{+})-[M(B_{c}(2S)^{\ast+})-M(B_{c}(2S)^{+})]$. Additionally, we present a study of $\Lambda^{0}_{b}$-baryon excited states, namely, $\Lambda_{b}(5912)^{0}$, $\Lambda_{b}(5920)^{0}$, $\Lambda_{b}(6146)^{0}$, and $\Lambda_{b}(6152)^{0}$, decaying into $\Lambda^{0}_{b}\pi^{+}\pi^{-}$.
