Popis: 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 ZH is excluded with mass below 2.76 TeV. Under these constrains, we study the Higgs–Gauge coupling production processes e+e−→ZH, e+e−→νeνe¯H and e+e−→e+e−H, top quark Yukawa coupling production process e+e−→tt¯H, Higgs self-couplings production processes e+e−→ZHH and e+e−→νeνe¯HH 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.
