Study of Excited $\Lambda _{b}^{0}$ States in the CMS Experiment
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}}{{(...
