dc.description.abstract | This dissertation describes a search for events with one top-quark and large
missing transverse momentum in the final state. Data collected during
2015 and 2016 by the ATLAS experiment from 13 TeV proton-proton collisions at the LHC corresponding to an integrated luminosity of 36.1 fb-1
are used. Two channels are considered, depending on the leptonic or the
hadronic decays of the W boson from the top quark. The obtained results
are interpreted in the context of simplifi ed models for dark-matter production and for the single production of a vector-like T quark. In the absence
of signi ficant deviations from the Standard Model background expectation,
95% con fidence-level upper limits on the corresponding production cross-
sections are obtained and these limits are translated into constraints on the
parameter space of the models considered. | en_US |
