| dc.description.abstract | A study of excited Λ0b 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 fb−1. The existence of four excited Λ0b states: Λ0b(5912)0, Λ0b(5920)0, Λ0b(6146)0, and Λ0b(6152)0 in the Λ0bπ+π− mass spectrum is confirmed, and their masses are measured. The Λ0bπ+π− mass distribution exhibits a broad excess of events in the region of 6040–6100MeV, whose origin cannot be discerned with the present data. | en_US |
