The search is optimised for pair production of vector-like top quarks in the Z(->nu nu) t + X decay channel. LHC pp collision data at a centre-of-mass energy of root S = 13 TeV recorded by the ATLAS detector in 2015 and 2016 are used, corresponding to an integrated luminosity of 36.1 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.", optnote="WOS:000408239700001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=3254), last updated on Mon, 11 Sep 2017 13:09:12 +0000", issn="1029-8479", doi="10.1007/JHEP08(2017)037", opturl="http://arxiv.org/abs/1705.10751", opturl="https://doi.org/10.1007/JHEP08(2017)037", archivePrefix="arXiv", eprint="1705.10751", language="English" }
