dc.description.abstract	A study of excited 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 140. The existence of four excited states: , , , and in the mass spectrum is confirmed, and their masses are measured. The mass distribution exhibits a broad excess of events in the region of 6040–6100 MeV, whose origin cannot be discerned with the present data.	en_US
