The data used correspond to an integrated luminosity of 4.9  fb−1 collected with the ATLAS detector at the Large Hadron Collider in proton-proton collisions at a center-of-mass energy of √s=7  TeV. In the diphoton mass range 110–150 GeV, the largest excess with respect to the background-only hypothesis is observed at 126.5 GeV, with a local significance of 2.8 standard deviations. Taking the look-elsewhere effect into account in the range 110–150 GeV, this significance becomes 1.5 standard deviations. The standard model Higgs boson is excluded at 95% confidence level in the mass ranges of 113–115 GeV and 134.5–136 GeV.}, 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 = {NRC Canada}, organization = {Canada Foundation for Innovation}, organization = {CERN}, organization = {Comision Nacional de Investigacion Cientifica y Tecnologica (CONICYT)}, organization = {Chinese Academy of Sciences}, organization = {Ministry of Science and Technology, China}, organization = {National Natural Science Foundation of China}, organization = {Departamento Administrativo de Ciencia, Tecnologia e Innovacion Colciencias}, organization = {Ministry of Education, Youth & Sports - Czech Republic Czech Republic Government}, organization = {DNRF Denmark}, organization = {Danish Natural Science Research Council}, organization = {Lundbeckfonden}, organization = {European Union (EU)}, organization = {European Union (EU) European Research Council (ERC)}, organization = {Centre National de la Recherche Scientifique (CNRS)}, organization = {CEA-DSM/IRFU, France}, organization = {GNAS, Georgia}, organization = {Federal Ministry of Education & Research (BMBF)}, organization = {Greek Ministry of Development-GSRT}, organization = {Israel Science Foundation}, organization = {MINERVA Israel}, organization = {German-Israeli Foundation for Scientific Research and Development}, organization = {DIP Israel}, 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) Netherlands Government}, organization = {Netherlands Organization for Scientific Research (NWO) Netherlands Government}, organization = {RCN, Norway}, organization = {Ministry of Science and Higher Education, Poland}, organization = {GRICES Portugal}, organization = {Portuguese Foundation for Science and Technology}, organization = {MERYS (MECTS), Romania}, organization = {MES of Russia}, organization = {ROSATOM}, 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 Sweden}, organization = {Wallenberg Foundation, Sweden}, organization = {SER Switzerland}, organization = {Swiss National Science Foundation (SNSF)}, organization = {Cantons of Bern, 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 = {Cantons of Geneva, Switzerland}, organization = {Russian Federation}, organization = {ICREA}, organization = {Science & Technology Facilities Council (STFC) ST/K001361/1 LHCb Upgrades ST/I003525/1 PP/E003699/2 ST/K001361/1 ST/I005803/1 GRIDPP ST/K001337/1 ST/K001361/1 LHCb ST/F007337/1 ST/I003142/1 ST/H001069/2 ST/K001248/1 ATLAS PP/E003087/1 ST/I000186/1 ST/M001431/1 ST/M001474/1 ST/H001093/2 ST/K00073X/1 ST/J004928/1 ST/L001144/1 ST/K001248/1 ST/I005803/1 ST/L000970/1 GRIDPP ST/K001418/1 ST/K003658/1 GRIDPP PP/E003699/1 ST/K001361/1 ATLAS ST/L000970/1 ATLAS Upgrade ST/K001361/1 ATLAS Upgrades ST/K001361/1 MINOS/MINOS+ ST/H001026/1 ST/G502320/1 ST/H001093/1 ST/I006080/1 ST/K001264/1 ATLAS ST/J004928/1 ATLAS Upgrade ST/J004944/1 ST/J005576/1 ST/K003658/1 ST/L001004/1 ST/K001329/1 ATLAS ST/I003517/1 ATLAS PP/E000347/1 ST/K001337/1 ATLAS ST/J002798/1 ST/H001026/2}, publisher = {American Physical Society}, title = {Search for the Standard Model Higgs Boson in the Diphoton Decay Channel with 4.9  fb−1 of pp Collision Data at √s=7  TeV with ATLAS}, doi = {10.1103/PhysRevLett.108.111803}, author = {Aad, G. and Aguilar Saavedra, Juan Antonio and Atlas Collaboration}, }
