@misc{10481/70623, year = {2021}, month = {8}, url = {http://hdl.handle.net/10481/70623}, abstract = {The production cross-section of a top quark in association with a W boson is measured using proton–proton collisions at √ s = 8 TeV. The dataset corresponds to an integrated luminosity of 20.2 fb−1, and was collected in 2012 by the ATLAS detector at the Large Hadron Collider at CERN. The analysis is performed in the single-lepton channel. Events are selected by requiring one isolated lepton (electron or muon) and at least three jets. A neural network is trained to separate the tW signal from the dominant t ¯t background. The cross-section is extracted from a binned profile maximum-likelihood fit to a two-dimensional discriminant built from the neural-network output and the invariant mass of the hadronically decaying W boson. The measured crosssection is σtW = 26 ± 7 pb, in good agreement with the Standard Model expectation.}, organization = {CERN}, organization = {ANPCyT}, organization = {YerPhI, Armenia}, organization = {Australian Research Council}, organization = {BMWFW}, organization = {Austrian Science Fund (FWF)}, organization = {Azerbaijan National Academy of Sciences (ANAS)}, organization = {SSTC, Belarus}, organization = {Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPQ) Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP)}, organization = {Natural Sciences and Engineering Research Council of Canada (NSERC) Canada Foundation for Innovation}, organization = {National Natural Science Foundation of China (NSFC)}, organization = {Departamento Administrativo de Ciencia, Tecnologia e Innovacion Colciencias}, organization = {Ministry of Education, Youth & Sports - Czech Republic}, organization = {MPO CR}, organization = {Czech Republic Government}, organization = {DNRF}, organization = {Danish Natural Science Research Council}, organization = {Centre National de la Recherche Scientifique (CNRS) CEA-DRF/IRFU, France}, organization = {Federal Ministry of Education & Research (BMBF)}, organization = {Max Planck Society}, organization = {Greek Ministry of Development-GSRT}, organization = {RGC and Hong Kong SAR, China}, organization = {Israel Science Foundation}, organization = {Benoziyo Center, Israel}, organization = {Istituto Nazionale di Fisica Nucleare (INFN)}, organization = {Ministry of Education, Culture, Sports, Science and Technology, Japan (MEXT) Ministry of Education, Culture, Sports, Science and Technology, Japan (MEXT) Japan Society for the Promotion of Science}, organization = {CNRST, Morocco; NWO, Netherlands}, organization = {RCN, Norway}, organization = {Ministry of Science and Higher Education, Poland NCN, Poland}, organization = {Portuguese Foundation for Science and Technology European Commission}, organization = {MNE/IFA, Romania}, organization = {Russian Federation}, organization = {Ministry of Education, Science & Technological Development, Serbia}, organization = {MSSR, Slovakia}, organization = {Slovenian Research Agency - Slovenia MIZS, Slovenia}, organization = {Spanish Government}, organization = {SRC}, organization = {Wallenberg Foundation, Sweden}, organization = {SNSF and Cantons of Bern and Geneva, Switzerland}, organization = {Ministry of Science and Technology, Taiwan}, organization = {Ministry of Energy & Natural Resources - Turkey}, organization = {UK Research & Innovation (UKRI)}, organization = {Science & Technology Facilities Council (STFC)}, organization = {CANARIE ComputeCanada}, organization = {Beijing Municipal Science & Technology Commission}, organization = {COST, ERC European Commission Marie Sklodowska-Curie Actions, European Union}, organization = {French National Research Agency (ANR)}, organization = {German Research Foundation (DFG)}, organization = {European Commission}, organization = {Alexander von Humboldt Foundation}, organization = {Greek NSRF, Greece}, organization = {BSF-NSF}, organization = {German-Israeli Foundation for Scientific Research and Development}, organization = {La Caixa Foundation CERCA Programme Generalitat de Catalunya}, organization = {PROMETEO Generalitat Valenciana}, organization = {Goran Gustafssons Stiftelse, Sweden}, organization = {Royal Society of London}, organization = {European Commission}, organization = {Leverhulme Trust}, organization = {NDGF (Denmark, Norway, Sweden)}, organization = {KIT/GridKA (Germany)}, organization = {INFN-CNAF (Italy)}, organization = {NL-T1 (Netherlands), PIC (Spain)}, organization = {ASGC (Taiwan)}, organization = {BNL (USA)}, publisher = {Springer}, title = {Measurement of single top-quark production in association with a W boson in the single-lepton channel at √ s = 8 TeV with the ATLAS detector}, doi = {10.1140/epjc/s10052-021-09371-7}, author = {Aad, G. and Aguilar Saavedra, Juan Antonio and Atlas Collaboration}, }
