The χb1ð3PÞ and χb2ð3PÞ states are observed through their ϒð3SÞγ decays, using an event sample of proton-proton collisions collected by the CMS experiment at the CERN LHC. The data were collected at a center-of-mass energy of 13 TeV and correspond to an integrated luminosity of 80.0 fb−1. The ϒð3S...
