We study the lepton flavor violating (LFV) processes l i →l j ν l ν ̄ l in the context of the topcolor-assisted technicolor (TC2) models. We find that the branching ratios B r (τ→l j ν τ ν ̄ τ ) are larger than the branching ratios B r (τ→l j ν l ν ̄ l ) in all of the parameter space. Over a wide range of parameter space, we have B r (τ→l j ν τ ν ̄ τ )∼10 −6 and B r (τ→l j ν l ν ̄ l )∼10 −9 ( l = μ or e ). Taking into account the bounds given by the experimental upper limit Br exp ( μ →3 e )⩽1×10 −12 on the free parameters of TC2 models, we further give the upper limits of the LFV processes l i →l j ν l ν ̄ 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.
