Using a data sample corresponding to an integrated luminosity of 4.4  fb−1, these states are reconstructed through their radiative decays to Υ(1S,2S) with Υ→μ+μ−. In addition to the mass peaks corresponding to the decay modes χb(1P,2P)→Υ(1S)γ, a new structure centered at a mass of 10.530±0.005(stat)±0.009(syst)  GeV is also observed, in both the Υ(1S)γ and Υ(2S)γ decay modes. This structure is interpreted as the χb(3P) system.}, organization = {ANPCyT}, organization = {YerPhI, Armenia}, organization = {Australian Research Council}, organization = {BMWF, Austria}, organization = {Azerbaijan National Academy of Sciences (ANAS)}, organization = {SSTC, Belarus}, organization = {National Council for Scientific and Technological Development (CNPq)}, organization = {Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP)}, organization = {Natural Sciences and Engineering Research Council of Canada}, organization = {National Research Centre (NRC)}, organization = {Canada Foundation for Innovation}, organization = {CERN}, organization = {Comision Nacional de Investigacion Cientifica y Tecnologica (CONICYT)}, organization = {Chinese Academy of Sciences}, organization = {MOST}, organization = {National Natural Science Foundation of China}, organization = {Departamento Administrativo de Ciencia, Tecnologia e Innovacion Colciencias}, organization = {Ministry of Education, Youth & Sports - Czech Republic}, organization = {MPO CR}, organization = {VSC CR}, organization = {Czech Republic Government}, organization = {DNRF}, organization = {Danish Natural Science Research Council}, organization = {Lundbeckfonden}, organization = {European Union (EU)}, organization = {Centre National de la Recherche Scientifique (CNRS)}, organization = {CEA-DSM/IRFU, France}, organization = {GNAS, Georgia}, organization = {Federal Ministry of Education & Research (BMBF)}, organization = {German Research Foundation (DFG)}, organization = {HGF}, organization = {Max Planck Society}, organization = {Alexander von Humboldt Foundation}, organization = {Greek Ministry of Development-GSRT}, organization = {Israel Science Foundation}, organization = {MINERVA}, organization = {German-Israeli Foundation for Scientific Research and Development}, organization = {DIP}, organization = {Benoziyo Center, Israel}, organization = {Istituto Nazionale di Fisica Nucleare (INFN)}, organization = {Ministry of Education, Culture, Sports, Science and Technology, Japan (MEXT) Japan Society for the Promotion of Science}, organization = {CNRST, Morocco}, organization = {FOM (The Netherlands)}, organization = {Netherlands Organization for Scientific Research (NWO) Netherlands Government}, organization = {RCN, Norway}, organization = {Ministry of Science and Higher Education, Poland}, organization = {GRICES}, organization = {Portuguese Foundation for Science and Technology}, organization = {MERYS (MECTS), Romania}, organization = {MES of Russia}, organization = {Russian Federation}, organization = {JINR}, organization = {MSTD, Serbia}, organization = {MSSR, Slovakia}, organization = {Slovenian Research Agency - Slovenia}, organization = {MVZT, Slovenia}, organization = {DST/NRF, South Africa}, organization = {Spanish Government}, organization = {SRC}, organization = {Wallenberg Foundation, Sweden}, organization = {SER}, organization = {Swiss National Science Foundation (SNSF)}, organization = {Cantons of Bern}, organization = {Geneva, Switzerland}, organization = {National Science Council of Taiwan}, organization = {Ministry of Energy & Natural Resources - Turkey}, organization = {Royal Society of London}, organization = {Leverhulme Trust}, organization = {United States Department of Energy (DOE)}, organization = {National Science Foundation (NSF)}, organization = {Science & Technology Facilities Council (STFC) ST/J004928/1 ST/K001361/1 MINOS/MINOS+ ST/K001337/1 ST/J002798/1 ST/L001004/1 ST/K003658/1 ST/K001248/1 ATLAS ST/J005576/1 ST/H001069/2 ST/I006080/1 ST/K001264/1 ATLAS PP/E000347/1 ST/K001361/1 LHCb Upgrades ST/K001361/1 ATLAS ST/K00073X/1 ST/I000186/1 PP/E003087/1 ST/H001026/1 ST/H001093/1 ST/I003142/1 ST/K001361/1 LHCb ST/K001361/1 ATLAS Upgrades PP/E003699/1 ST/I005803/1 GRIDPP ST/L001144/1 ST/M001431/1 GRIDPP ST/K001361/1 ST/J004944/1 ST/G502320/1 ST/F007337/1 ST/I003525/1 PP/E003699/2 ST/H001026/2 ST/H001093/2 ST/J004928/1 ATLAS Upgrade ST/L000970/1 ST/K001329/1 ATLAS ST/L000970/1 ATLAS Upgrade ST/K001337/1 ATLAS ST/I003517/1 ST/I005803/1 ST/K003658/1 GRIDPP ATLAS ST/K001248/1}, organization = {ICREA}, publisher = {American Physical Society}, title = {Observation of a New χb State in Radiative Transitions to Υ(1S) and Υ(2S) at ATLAS}, doi = {10.1103/PhysRevLett.108.152001}, author = {Aad, G. and Aguilar Saavedra, Juan Antonio and Atlas Collaboration}, }
