Abstract

In the framework of the Left-Right twin Higgs (LRTH) model, we consider the constrains from the latest search for high-mass dilepton resonances at the LHC and find that the heavy neutral boson Z_H is excluded with mass below 2.76 TeV. Under these constrains, we study the Higgs-Gauge coupling production processes e⁺e^-→ ZH, e⁺e^-→ ν_eν_eH and e⁺e^-→ e⁺e^-H, top quark Yukawa coupling production process e⁺e^-→ ttH, Higgs self-couplings production processes e⁺e^-→ ZHH and e⁺e^-→ ν_eν_eHH at e⁺e^- colliders. Besides, we study the major decay modes of the Higgs boson, namely h→ ff(f=b,c,τ), VV^*(V=W, Z), gg, γγ. We find that the LRTH effects are sizable so that the Higgs boson processes at e⁺e^- collider can be a sensitive probe for the LRTH model.
