The left-right twin Higgs (LRTH) model is a concrete realization of the twin Higgs mechanism, which predicts the existence of a new heavy top quark (T) and charged Higgs boson (ϕ±). Detecting of these new particles in the LRTH model depends on free parameters (f, f̂, M) which are constrained by the electroweak precision measurments. We study the associated production of a charged Higgs boson (ϕ+) and a heavy top quark (T) via e− e+→ϕ+T̅b in the framework the LRTH model at √s=3000GeV and yearly integrated luminosity of L=500 fb−1. We find that the production cross section of the process e−e+→ϕ+T̅b can reach to the level of several tens fb and a statical significance of 5σ can be achieved in the suitable parameter space of the LRTH model at √s=3000GeV.
