Abstract: The vector-like top quark T is an important new fermion beyond the Standard Model. In the framework of a simplified model, we study the possibility of detecting the T through the single production of T decaying into tZ with Z decaying to neutrinos at the 14 TeV Large Hadron Collider (LHC). This simplified model includes three free parameters, that is the coupling constant g⁎, the T quark mass mT and the mixing parameter RL. In order to investigate the observability of the single T production, we make a detailed detector simulation and scan the parameter space. Corresponding to an integrated luminosity of 3000 fb−1, the correlated regions g⁎∈[0.14,0.5]([0.2,0.5]) with mT∈[1200GeV,1900GeV]([1200GeV,1660GeV]) can be excluded (discovered) for RL=0 and the correlated regions g⁎∈[0.1,0.5] with mT∈[1600GeV,2520GeV]([1320GeV,2220GeV]) can be excluded (discovered) for RL=0.5.
