The search is based on 139.0 $\\pm$ 2.4 fb$^{-1}$ of pp collisions at $\\sqrt{s}$ = 13 TeV recorded in 2015-2018 with the ATLAS detector at the CERN Large Hadron Collider.  Data are analysed in the fully hadronic top quark final state, with a focus on the high LQ mass regime for which the top quarks tend to be boosted. The search results are interpreted to provide a limit on the leptoquark mass. Mass limits on leptoquark pair production are also set as a function of the leptoquark decay branching ratio into a charged lepton and a top quark, as opposed to a neutrino and a bottom quark. \n\nBasic event selection:\n- == 2 opposite-sign same-flavour leptons: pT > 100 GeV, in fiducial volume, isolated from jets \n- >= 2 large-radius jets\n- dilepton invariant mass > 120 GeV\n\nA parameterized boosted decision tree classifier is used to optimize the sensitivity to LQ signal, using event kinematics and jet substructure variables (see paper).","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.96389.v1/t1","@type":"Dataset","description":"Expected and observed upper limits at the 95% CL on the leptoquark pair production cross section as a function of...","name":"Table 1: LQLQ->tete Cross Section Limit"},{"@id":"https://doi.org/10.17182/hepdata.96389.v1/t2","@type":"Dataset","description":"Expected and observed upper limits at the 95% CL on the leptoquark pair production cross section as a function of...","name":"Table 2: LQLQ->tmutmu Cross Section Limit"},{"@id":"https://doi.org/10.17182/hepdata.96389.v1/t3","@type":"Dataset","description":"Expected and observed 95% CL lower limits on the leptoquark mass as a function of the branching ratio $\\mathcal{B}$(LQ->$te$).","name":"Table 3: Limit on LQ mass vs. B(LQ->te)"},{"@id":"https://doi.org/10.17182/hepdata.96389.v1/t4","@type":"Dataset","description":"Expected and observed 95% CL lower limits on the leptoquark mass as a function of the branching ratio $\\mathcal{B}$(LQ->$t\\mu$).","name":"Table 4: Limit on LQ mass vs. B(LQ->tmu)"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1821703?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/96389"}],"inLanguage":"en","name":"Search for pair production of scalar leptoquarks decaying into first- or second-generation leptons and top quarks in proton-proton collisions at $\\sqrt{s}$ = 13 TeV with the ATLAS detector","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1821703?version=1","version":1}
