A search for pair production of a scalar partner of the top quark in events with four or more jets plus missing transverse momentum is presented. An analysis of 36.1 fb?1 of s=13 TeV proton-proton collisions collected using the ATLAS detector at the LHC yields no significant excess over the expected Standard Model background. To interpret the results a simplified supersymmetric model is used where the top squark is assumed to decay via t˜1?t(?)?˜10 and t˜1?b?˜1±?bW(?)?˜10, where ?1 0(?1 ±) denotes the lightest neutralino (chargino). Exclusion limits are placed in terms of the top-squark and neutralino masses. Assuming a branching ratio of 100% to t?˜10, top-squark masses in the range 450–1000 GeV are excluded for ?˜10 masses below 160 GeV. In the case where mt˜1?mt+m?˜10, top-squark masses in the range 235–590 GeV are excluded. © 2017, The Author(s). ; Austrian Science Fund Fundação de Amparo à Pesquisa do Estado de São Paulo Narodowe Centrum Nauki Ministerstwo Nauki i Szkolnictwa Wyższego Australian Research Council Bundesministerium für Wissenschaft, Forschung und Wirtschaft Council on grants of the President of the Russian Federation Fundação para a Ciência e a Tecnologia Joint Institute for Nuclear Research National Natural Science Foundation of China Bundesministerium für Bildung und Frauen Natural Sciences and Engineering Research Council of Canada Ministerstvo Zdravotnictví Ceské Republiky Israeli Centers for Research Excellence Istituto Nazionale di Fisica Nucleare Ministry of Science and Technology Nederlandse Organisatie voor Wetenschappelijk Onderzoek Comisión Nacional de Investigación Científica y Tecnológica Danmarks Grundforskningsfond Conselho Nacional de Desenvolvimento Científico e Tecnológico Shota Rustaveli National Science Foundation Chinese Academy of Sciences Departamento Administrativo de Ciencia, Tecnología e Innovación (COLCIENCIAS) Iowa Science Foundation CERN Javna Agencija za Raziskovalno Dejavnost RS Arizona-Nevada Academy of Science General Secretariat for Research and Technology Ministry of Education, Culture, Sports, Science and Technology National Rehabilitation Center IN2P3-CNRS Japan Society for the Promotion of Science National Research Center "Kurchatov Institute" Agencia Nacional de Promoción Científica y Tecnológica Helmholtz-Gemeinschaft Canada Foundation for Innovation Centre National pour la Recherche Scientifique et Technique Generalitat de Catalunya Royal Society British Columbia Knowledge Development Fund Glycemic Index Foundation Marianne and Marcus Wallenberg Foundation Horizon 2020 Ministry of Science and Technology of the People's Republic of China Leverhulme Trust Generalitat Valenciana Agence Nationale de la Recherche Fonds Québécois de la Recherche sur la Nature et les Technologies Deutsche Forschungsgemeinschaft Ontario Innovation Trust Fondation Partager le Savoir European Commission European Regional Development Fund Canarie U.S. Department of Energy Bloom's Syndrome Foundation Banting Research Foundation Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung Singapore Eye Research Institute Compute Canada European Research Council National Science Foundation Science and Technology Facilities Council Ministerio de Economía y Competitividad CRC Health Group ; We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWFW and FWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF and DNSRC, Denmark; IN2P3-CNRS, CEA-DSM/IRFU, France; SRNSF, Georgia; BMBF, HGF, and MPG, Germany; GSRT, Greece; RGC, Hong Kong SAR, China; ISF, I-CORE and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; NWO, Netherlands; RCN, Norway; MNiSW and NCN, Poland; FCT, Portugal; MNE/IFA, Romania; MES of Russia and NRC KI, Russian Federation; JINR; MESTD, Serbia; MSSR, Slovakia; ARRS and MIZS?, Slovenia; DST/NRF, South ; Africa; MINECO, Spain; SRC and Wallenberg Foundation, Sweden; SERI, SNSF and Cantons of Bern and Geneva, Switzerland; MOST, Taiwan; TAEK, Turkey; STFC, United Kingdom; DOE and NSF, United States of America.
