The standard model(SM) is based on the group SU(3)cxSU(2)LxU(1)Y gauge symmetries and Higgs mechanism in particle physics. Although it has been proved by a lot of experiments, we have not found the Higgs boson which cause the symmetry break spontaneously. SM describes strong, weak and electromagnetic interactions. SM predicts the neutrinos are massless, but solar and atmospheric experiments directly show that the neutrinos have mass and there are oscillation within the different generations. So SM is not perfect and it also has other problems, such as too many free parameters, triviality, and unnaturalness, etc. So people proposed some new physics to solove the SM problems. The seesaw mechanism can explain the neutrinos mass problem, at the same time it predicts a heavy lepton's existence. Many new physics models have been discussed the heavy lepton problem, such as technicolor model, Little Higgs model. In this paper, on the base of seesawâ…¢study the heavy lepton and Higgs boson prodution. We calaculate the cross sections of these processes and give some discussions. These results offer some data for study Higgs boson. And this is important for the ILC experiment test of the Higgs boson.
