The $\\chi_{b1}(3P)$ and $\\chi_{b2}(3P)$ states are observed through their $\\Upsilon(3S)$ $\\gamma$ 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 $\\Upsilon(3S)$ mesons are identified through their dimuon decay channel, while the low-energy photons are detected after converting to e+e- pairs in the silicon tracker, leading to a $\\chi_{b}(3P)$ mass resolution of 2.2 MeV. This is the first time that the J=1 and 2 states are well resolved and their masses individually measured: 10513.42$\\pm$0.41(stat)$\\pm$0.18(syst) MeV and 10524.02$\\pm$0.57(stat)$\\pm$0.18(syst) MeV; they are determined with respect to the world-average value of the $\\Upsilon(3S)$ mass, which has an uncertainty of 0.5 MeV. The mass splitting is measured to be 10.60$\\pm$0.64(stat)$\\pm$0.17(syst) MeV.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.85742.v1/t1","@type":"Dataset","description":"Observation of the $\\chi_{b1}(3P)$ and $\\chi_{b2}(3P)$ and measurement of their masses.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.85742.v1/t2","@type":"Dataset","description":"Observation of the $\\chi_{b1}(3P)$ and $\\chi_{b2}(3P)$ and mass splitting measurement.","name":"Table 2"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1675256?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/85742"}],"inLanguage":"en","name":"Observation of the $\\chi_\\mathrm{b1}$(3P) and $\\chi_\\mathrm{b2}$(3P) and measurement of their masses","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1675256?version=1","version":1}
