Search for singly produced Z^′ boson decaying into T^′ t at the CMS experiment — •Anna Benecke, Johannes Haller, and Roman Kogler — Institut für Experimentalphysik, Universität Hamburg

Many models of physics beyond the standard model predict vector-like quarks (T^′) and in addition a new heavy gauge boson (Z^′). While decays of the Z^′ and T^′ into standard model particles have been studied already, no experimental results for the decay Z^′ → T^′ t are avaible so far. In this talk a search for singly produced Z^′ bosons decaying into T^′ t in pp collisions at √s=13 TeV is presented. The analysis is performed in the lepton + jets channel. Two decay channels of the T^′ into the Higgs boson and a top quark or a Z boson and a top quark are considered. For this purpose the full dataset collected by the CMS experiment at √s=13 TeV is used. The status of this analysis will be shown, including the event selection and the reconstruction of the decay chain.
