The new vector-like quarks are predicted by several new physics beyond the Standard Model at the TeV scale. In this paper, we study single production of vector-like quark T with electric charge |Q|=2/3 in the framework of a simplified model. We investigate the discovery potential of heavy vector-like T-quark decaying into a top quark and a Z boson in trilepton final states, at the future 100 TeV pp colliders including the realistic detector effects. The 95% confidence level (CL) excluded regions and the 5σ discovery reach in the parameter plane between the mass of T-quark and the coupling parameter g⁎, are obtained at a 100 TeV pp collider with the integrated luminosity of 30 ab−1. The projected sensitivity in terms of the production cross section times branching fraction is also predicted for 5% systematic uncertainty.
