摘要

In the context of the left-right twin Higgs (LRTH) model, we fist study single production of the standard model (SM) top quark via e-γ collisions. We find that the corrections of the LRTH model to the cross section of the process e-γ→ vebt might be observed only for f ≤ 750 GeV and the heavy top quark mass scale M ≥ 500 GeV in future integrated luminosity of ￡=100 fb-1. We also consider single production of the heavy top quark T via e-γ collisions. Our numerical results show that the possible signals of the heavy top quark T might be observed via the decay channel T→φ+b→tbb in future LC experiment with ∫8=3 TeV and ￡=500fb-1.
