@misc{10481/85171, year = {2023}, month = {6}, url = {https://hdl.handle.net/10481/85171}, abstract = {A measurement of single top-quark production in the s-channel is performed in proton–proton collisions at a centre-of-mass energy of 13 TeV with the ATLAS detector at the CERN Large Hadron Collider. The dataset corresponds to an integrated luminosity of 139 fb−1. The analysis is performed on events with an electron or muon, missing transverse momentum and exactly two b-tagged jets in the final state. A discriminant based on matrix element calculations is used to separate single-top-quark s-channel events from the main background contributions, which are top-quark pair production and W-boson production in association with jets. The observed (expected) signal significance over the background-only hypothesis is 3.3 (3.9) standard deviations, and the measured cross-section is pb, consistent with the Standard Model prediction of pb.}, 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 = {Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPQ)}, organization = {Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP)}, organization = {Natural Sciences and Engineering Research Council of Canada (NSERC)}, organization = {NRC, Canada}, organization = {Canada Foundation for Innovation}, organization = {CERN}, organization = {ANID, Chile}, organization = {Chinese Academy of Sciences}, organization = {Ministry of Science and Technology, China}, organization = {National Natural Science Foundation of China (NSFC)}, organization = {Minciencias, Colombia}, organization = {MEYS CR, Czech Republic}, organization = {National Research Foundation of Korea}, organization = {Danish Natural Science Research Council}, organization = {Centre National de la Recherche Scientifique (CNRS)}, organization = {CEA-DRF/IRFU, France}, organization = {SRNSFG, Georgia}, organization = {Federal Ministry of Education & Research (BMBF)}, organization = {HGF, Germany}, organization = {Max Planck Society}, organization = {GSRI, Greece}, organization = {RGC, China}, organization = {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)}, organization = {Ministry of Education, Culture, Sports, Science and Technology, Japan (MEXT) Japan Society for the Promotion of Science}, organization = {CNRST, Morocco}, organization = {Netherlands Organization for Scientific Research (NWO) Netherlands Government}, organization = {RCN, Norway}, organization = {MEiN, Poland}, organization = {Fundacao para a Ciencia e a Tecnologia (FCT)}, organization = {MNE/IFA, Romania}, organization = {Ministry of Education, Science & Technological Development, Serbia}, organization = {MSSR, Slovakia}, organization = {Slovenian Research Agency -
