摘要：
In this letter, we analyze the prospects of observing the new vector-like T-quark in the leptonic T -> bW decay channel at the Large Hadron Electron Collider (LHeC). The results show that the mixing between the T-quark with the first generation quarks can largely enhance the production cross section. We further study the observability of the single T through the process e(+) p -> T(-> bW(+))(v) over bar (e) -> b(e)(+) + is not an element of(miss)(T) at the LHeC with the proposed 140 GeV electron beam (with 80% polarization) and 7 TeV proton beam. To be as model-independent as possible, a simplified model method with only two free parameters (g* and R-L) has been applied. For three typical T-quark masses, the 3 sigma exclusion limits as well as the 5 sigma discovery region are respectively presented in terms of parameter space regions. (C) 2017 The Author(s).
