Associated production of charged higgs boson and heavy top quark in the left-right twin higgs model at high energye-e+ collider

Abstract

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 (phi(+/-)). Detecting of these new particles in the LRTH model depends on free parameters (f, (f) over cap, M) which are constrained by the electroweak precision measurments. We study the associated production of a charged Higgs boson (phi(+)) and a heavy top quark (T) via e(-)e(+) -> phi(+)(T) over barb in the framework the LRTH model at root s=3000 GeV and yearly integrated luminosity of L=500 fb(-1). We find that the production cross section of the process e(-)e(+)-> phi(+)(T) over barb can reach to the level of several tens fb and a statical significance of 5 sigma can be achieved in the suitable parameter space of the LRTH model at root s=3000 GeV.
