The flaw in the Standard Model cause an advance of a variety of new physical Models, which will be tested by LHC and ILC.In this paper, we will introduce the basic structure briefly by the Standard Model, indicate some flaws in it and several important new physics Model. Then, we will describe the DLRM II Model and discuss how a fewμandÏ„limit the neutrino experimental data in the lepton flavor decay. Finally, I have calculated the scattering of e+e-â†'ξR+ξR- in ILC in derail. The main results include the followings:(1)μâ†'eee,Ï„â†'μμμ,Ï„â†'μee have been reduced naturally,which differ from the primary DLRM. In addition,the dark matter candidate n is such a dirac that it can not help induce signal to damage the scattering process(e-e-â†'ξR-ξR-) of fermions.(2) The process ofμâ†'eγhas strict limits to the model,which requires essentially the third generation of degenerate n to be degenerated. This conclusion is very different from existing literature.(3)In a variety of parameters allowed, the scattering section of e+e-â†'ξR+ξR- can reach up to hundreds of fb. The most contribution comes from the t channel of exchanging n.And therefore, it can be observed very promisingly in ILC.
