The results of a search for vector-like top quarks using events with exactly one lepton, at least four jets, and large missing transverse momentum are reported. The search is optimised for pair production of vector-like top quarks in the $Z(\\rightarrow \\! \\! \\nu \\nu) \\, t + X$ decay channel. LHC \\textit{pp} collision data at a centre-of-mass energy of $\\sqrt{s}=13$ TeV recorded by the ATLAS detector in 2015 and 2016 are used, corresponding to an integrated luminosity of 36.1 $\\mathrm{fb}^{-1}$. No significant excess over the Standard Model expectation is seen and upper limits on the production cross-section of a vector-like $T$ quark pair as a function of the $T$ quark mass are derived. The observed (expected) 95\\% CL lower limits on the $T$ mass are 870 GeV (890 GeV) for the weak-isospin singlet model, 1.05 TeV (1.06 TeV) for the weak-isospin doublet model and 1.16 TeV (1.17 TeV) for the pure $Zt$ decay mode. Limits are also set on the mass as a function of the decay branching ratios, excluding large parts of the parameter space for masses below 1 TeV.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.77266.v1/t1","@type":"Dataset","description":"Expected and observed 95% CL upper limit on the cross-section times branching ratio for VLQ $T$ pair production as a...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.77266.v1/t2","@type":"Dataset","description":"Expected and observed 95% CL upper limit on the cross-section times branching ratio for VLQ $T$ pair production as a...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.77266.v1/t3","@type":"Dataset","description":"Expected and observed 95% CL upper limit on the cross-section times branching ratio for VLQ $T$ pair production as a...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.77266.v1/t4","@type":"Dataset","description":"Expected 95% CL lower limit on the VLQ $T$ mass as a function of the decay branching ratios into $W...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.77266.v1/t5","@type":"Dataset","description":"Observed 95% CL lower limit on the VLQ $T$ mass as a function of the decay branching ratios into $W...","name":"Table 5"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1601647?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/77266"}],"inLanguage":"en","name":"Search for pair production of vector-like top quarks in events with one lepton, jets, and missing transverse momentum in $\\sqrt{s} = 13$ TeV pp collisions with the ATLAS detector","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1601647?version=1","version":1}
