@misc{10481/63095, year = {2016}, month = {3}, url = {http://hdl.handle.net/10481/63095}, abstract = {This paper reports a detailed study of techniques for identifying boosted, hadronically decaying W bosons using 20.3 fb−1 of proton–proton collision data collected by the ATLAS detector at the LHC at a centre-of-mass energy s√=8TeV. A range of techniques for optimising the signal jet mass resolution are combined with various jet substructure variables. The results of these studies in Monte Carlo simulations show that a simple pairwise combination of groomed jet mass and one substructure variable can provide a 50 % efficiency for identifying W bosons with transverse momenta larger than 200 GeV while maintaining multijet background efficiencies of 2–4 % for jets with the same transverse momentum. These signal and background efficiencies are confirmed in data for a selection of tagging techniques.}, organization = {ANPCyT}, organization = {YerPhI, Armenia}, organization = {Australian Research Council}, organization = {BMWFW, Austria}, organization = {Austrian Science Fund (FWF)}, 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 = {IN2P3-CNRS, CEA-DSM/IRFU, France}, organization = {GNSF, Georgia}, organization = {Federal Ministry of Education & Research (BMBF)}, organization = {HGF, Germany}, organization = {Max Planck Society}, organization = {Greek Ministry of Development-GSRT}, organization = {Hong Kong Research Grants Council}, organization = {Israel Science Foundation}, organization = {I-CORE, 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 = {NCN, Poland}, organization = {Portuguese Foundation for Science and Technology}, organization = {MNE/IFA, Romania}, organization = {Russian Federation}, organization = {NRC KI, Russian Federation}, organization = {JINR}, organization = {MESTD, Serbia}, organization = {MSSR, Slovakia}, organization = {Slovenian Research Agency - Slovenia}, organization = {MIZS, Slovenia}, organization = {DST/NRF, South Africa}, organization = {MINECO, Spain}, organization = {SRC, Sweden}, organization = {Wallenberg Foundation, Sweden}, organization = {SERI, Switzerland}, organization = {Swiss National Science Foundation (SNSF)}, organization = {Canton of Bern, Switzerland}, organization = {Canton of Geneva, Switzerland}, organization = {Ministry of Science and Technology, Taiwan}, organization = {Ministry of Energy & Natural Resources - Turkey}, organization = {Science & Technology Facilities Council (STFC)}, organization = {United States Department of Energy (DOE)}, organization = {National Science Foundation (NSF)}, organization = {BCKDF, Canada}, organization = {Canada Council, Canada}, organization = {CANARIE, Canada}, organization = {CRC, Canada}, organization = {Compute Canada, Canada}, organization = {FQRNT}, organization = {Ontario Innovation Trust, Canada}, organization = {European Union (EU)}, organization = {European Union (EU) European Research Council (ERC)}, organization = {Horizon, European Union}, organization = {French National Research Agency (ANR)}, organization = {Region Auvergne-Rhone-Alpes}, organization = {Fondation Partager le Savoir, France}, organization = {German Research Foundation (DFG)}, organization = {Alexander von Humboldt Foundation}, organization = {Herakleitos programme - EU-ESF}, organization = {Thales programme - EU-ESF}, organization = {Aristeia programme - EU-ESF}, organization = {Greek Ministry of Development-GSRT}, organization = {US-Israel Binational Science Foundation}, organization = {German-Israeli Foundation for Scientific Research and Development}, organization = {Minerva, Israel}, organization = {BRF, Norway}, organization = {Royal Society of London}, organization = {Leverhulme Trust}, organization = {ICREA}, publisher = {Springer Nature}, title = {Identification of boosted, hadronically decaying W bosons and comparisons with ATLAS data taken at s√=8 TeV}, doi = {10.1140/epjc/s10052-016-3978-z}, author = {Aad, G. and Aguilar Saavedra, Juan Antonio and Atlas Collaboration}, }
