Abstract

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.
