@misc{10481/75868, year = {2022}, month = {5}, url = {http://hdl.handle.net/10481/75868}, abstract = {A search is made for a vectorlike T quark decaying into a Higgs boson and a top quark in 13 TeV protonproton collisions using the ATLAS detector at the Large Hadron Collider with a data sample corresponding to an integrated luminosity of 139 fb−1. The Higgs-boson and top-quark candidates are identified in the all-hadronic decay mode, where H → b¯b and t → bW → bq¯q0 are reconstructed as large-radius jets. The candidate Higgs boson, top quark, and associated B hadrons are identified using tagging algorithms. No significant excess is observed above the background, so limits are set on the production cross section of a singlet T quark at 95% confidence level, depending on the mass mT and coupling κT of the vectorlike T quark to Standard Model particles. In the considered mass range between 1.0 and 2.3 TeV, the upper limit on the allowed coupling values increases with mT from a minimum value of 0.35 for 1.07 < mT < 1.4 TeV to 1.6 for mT ¼ 2.3 TeV.}, organization = {ANPCyT}, organization = {YerPhI, Armenia}, organization = {Australian Research Council}, organization = {BMWFW, Austria 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) NRC, Canada Canada Foundation for Innovation}, organization = {CERN}, organization = {ANID, Chile}, organization = {Chinese Academy of Sciences}, organization = {MOST, Canada NSFC, Canada}, organization = {Minciencias, Colombia}, organization = {MEYS CR, Czech Republic}, organization = {DNRF, Denmark Danish Natural Science Research Council}, organization = {Centre National de la Recherche Scientifique (CNRS) CEA-DRF/IRFU, France}, organization = {SRNSFG, Georgia}, organization = {Federal Ministry of Education & Research (BMBF) HGF, Germany Max Planck Society}, organization = {GSRI, Greece}, organization = {RGC, China Hong Kong SAR, China}, organization = {Israel Science Foundation 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}, organization = {Netherlands Organization for Scientific Research (NWO) Netherlands Government}, organization = {RCN, Norway}, organization = {MEiN, Poland}, organization = {Portuguese Foundation for Science and Technology European Commission}, organization = {MNE/IFA, Romania}, organization = {JINR}, organization = {Russian Federation NRC KI, Russian Federation}, organization = {Ministry of Education, Science & Technological Development, Serbia}, organization = {MSSR, Slovakia}, organization = {Slovenian Research Agency - Slovenia MIZS, Slovenia}, organization = {DSI/NRF, South Africa}, organization = {Spanish Government}, organization = {SRC, Sweden Wallenberg Foundation, Sweden}, organization = {SERI, Switzerland Swiss National Science Foundation (SNSF) Canton of Bern, Switzerland Canton of 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) United States Department of Energy (DOE) National Science Foundation (NSF)}, organization = {BCKDF, Canada CANARIE, Canada Compute Canada, Canada CRC, Canada}, organization = {COST, European Union European Research Council (ERC) ERDF, European Union Horizon 2020, European Union Marie SklodowskaCurie Actions, European Union}, organization = {French National Research Agency (ANR)}, organization = {German Research Foundation (DFG) Alexander von Humboldt Foundation}, organization = {Herakleitos program Thales Group Aristeia program European Commission Greek NSRF, Greece}, organization = {BSF-NSF, Israel German-Israeli Foundation for Scientific Research and Development}, organization = {Norwegian Financial Mechanism 2014-2021, Norway}, organization = {NCN, Poland Polish National Agency for Academic Exchange (NAWA)}, organization = {La Caixa Banking Foundation, Spain CERCA Programme Generalitat de Catalunya, Spain PROMETEO Programme Generalitat Valenciana, Spain GenT Programme Generalitat Valenciana, Spain}, organization = {Goran Gustafssons Stiftelse, Sweden}, organization = {Royal Society of London Leverhulme Trust}, publisher = {American Physical Society}, title = {Search for single production of a vectorlike T quark decaying into a Higgs boson and top quark with fully hadronic final states using the ATLAS detector}, doi = {10.1103/PhysRevD.105.092012}, author = {Aad, G. and Aguilar Saavedra, Juan Antonio and Rodríguez Chala, Mikael and Atlas Collaboration}, }
