Abstract：
We study the lepton flavor violating (LFV) processes l-i→l-jν-l-l in the context of the topcolor-assisted technicolor (TC2) models. We find that the branching ratios Br(τ→l-jν-τ-τ) are larger than the branching ratios Br(τ→l-jν-l-l) in all of the parameter space. Over a wide range of parameter space, we have Br(τ→l-jν-τ-τ)～10-6 and Br(τ→l-jν-l-l)～10-9(l=μ or e). Taking into account the bounds given by the experimental upper limit Brexp(μ→3e)≤1×10-12 on the free parameters of TC2 models, we further give the upper limits of the LFV processes l-i→l-jν-l-l. We hope that the results may be useful to partly explain the data of the neutrino oscillations and the future neutrino experimental data might be used to test TC2 models.
