Study of e~+e~-→τ~+μ~- in the LH Model
Zhang Yi-ning · Journal of Hebei Normal University · 2011
The cross section for the process e~+e~-→τ~+μ~- is enhanced significantly in the littlest Higgs model(LH model),by the one-loop contribution which involves the flavor change coupling between the mirror lepton and the standard model(SM) lepton from the vertex angle of τ+μ-Z(γ).The process e~+e~-→τ~+μ~- within the LH model is investigated.Reasonable numerical result of σ is obtained by using High Energy Physics and Loop Tools in Mathematica 7.0.It can be observed at future e+e-linear colliders,which is in favor of testing the LH model.
