      abstract     = {In this work, events in which a single top quark is
                      produced in association with a Z-boson are investigated.
                      Particular focus is on final states in which two leptons
                      originate from the Z boson and the top quark decays
                      hadronically. The analysis uses data collected with the
                      Compact Muon Solenoid (CMS) detector between 2016 and 2018,
                      corresponding to an integrated luminosity of 137 fb$^-$$^1$;
                      data are produced from proton-proton collisions at the Large
                      Hadron Collider (LHC), with a center of mass energy equal to
                      13 TeV. The discrimination between signal and backgrounds is
                      optimized by testing different methods for the event
                      reconstruction and with the implementation of a Deep Neural
                      Network (DNN). In the last part of the analysis, a
                      statistical fit is performed to the DNN output for the
                      signal extraction, reaching an expected significance of the
                      $\it tZq$ signal overbackground of 2.4o.},
