Study of excited ?b0 states decaying to ?b0?+?- in proton-proton collisions at ?s=13TeV

Abstract: A study of excited ?b0 baryons is reported, based on a data sample collected in 2016?2018 with the CMS detector at the LHC in proton-proton collisions at a center-of-mass energy of 13?TeV, corresponding to an integrated luminosity of up to 140fb-1. The existence of four excited ?b0 states: ?b0(5912)0, ?b0(5920)0, ?b0(6146)0, and ?b0(6152)0 in the ?b0?+?- mass spectrum is confirmed, and their masses are measured. The ?b0?+?- mass distribution exhibits a broad excess of events in the region of 6040?6100?MeV, whose origin cannot be discerned with the present data.
