中文摘要：

We investigate the associated production of the neutral top-Higgs h_t～0 with a pair of top-quarks in the context of the topcolor-assisted technicolor (TC2) model at the future e+e-Linear Colliders (LC) i.e.e+e-→t(-|t)h_t～0.We calculate the production rate and present the distributions of the transverse momenta of top-Higgs and top-quarks.The results show that the total cross section is typically of the order of 1.0-7.5 fb in the energy range between 1000 GeV and 2000 GeV of the LC for the whole top-Higgs mass region of interest.It should be distinctly possible that hundreds or even thousands of ht0 signals can be produced per year at the LC given the luminosity L= 500 fb-1.

We investigate the associated production of the neutral top-Higgs ht^0 with a pair of top-quarks in the context of the topcolor-assisted technicolor （TC2） model at the future e＋e- Linear Colliders （LC） i.e. e＋e- → ttht^0. We calculate the production rate and present the distributions of the transverse momenta of top-Higgs and top-quarks. The results show that the total cross section is typically of the order of 1.0 7.5 fb in the energy range between 1000 GeV and 2000 GeV of the LC for the whole top-Higgs mass region of interest. It should be distinctly possible that hundreds or even thousands of ht^0 signals can be produced per year at the LC given the luminosity L = 500 fb^-1.
