| Özet |
| A study of excited Λ b 0 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 Λ b 0 states: Λ b 0 (5912) 0, Λ b 0 (5920) 0, Λ b 0 (6146) 0, and Λ b 0 (6152) 0 in the Λ b 0 π+ π− mass spectrum is confirmed, and their masses are measured. The Λ b 0 π+ π− mass distribution exhibits a broad excess of events in the region of 6040–6100 MeV, whose origin cannot be discerned with the present data. |
