Search for the vector-like top quark $T$ at the future linac-ring type $ep$ collider

The little Higgs models typically contain a new vector-like top quark $T$, which plays a key role in breaking the electroweak symmetry. In the context of the littlest Higgs (LH) model, we study single production of this kind of new particle via the process $ep\to eb\to {\nu }_{e}T$ in the future linac-ring type $ep$ collider (LC$⨂LHC$). We find that the production cross section is in the range of $1.2\times {10}^{-4}$– 0.48 $pb$ at the $LC⨂LHC$ with $\sqrt{s}=3.7$ $TeV$.
