Özet
The and states are observed through their ϒ(3S)γ 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 . The ϒ(3S) mesons are identified through their dimuon decay channel, while the low-energy photons are detected after converting to pairs in the silicon tracker, leading to a mass resolution of 2.2 MeV. This is the first time that the and 2 states are well resolved and their masses individually measured: and ; they are determined with respect to the world-average value of the ϒ(3S) mass, which has an uncertainty of 0.5 MeV. The mass splitting is measured to be .
