Lepton flavor violating (LFV) processes, [Formula: see text] and [Formula: see text] ([Formula: see text] or [Formula: see text]), via four-Fermi contact interactions at future International Linear Collider (ILC) are studied. Taking account of previous experimental results of LFV processes [Formula: see text] and [Formula: see text], we find that the upper limits on the LFV parameters for [Formula: see text] could be improved at the ILC experiment using the polarized electron beam. The improvement of the upper limits could be nearly an order of magnitude as compared to previous ones.

Lepton flavor violating (LFV) decays of charged leptons \(\mu\rightarrow e\gamma\)  and SM-like Higgs boson \(h\rightarrow \mu\tau\) are discussed in the framework of the  economical 3-3-1 model  adding three additional singlets neutrinos (E331\(X_R\)). We will show that the appearance of new neutrinos and charged Higgs bosons in this model can result in interesting regions of the parameter space, which satisfy  the recent experimental bound of \(Br(\mu\rightarrow e\gamma)\)  as well as give large \(Br(h\rightarrow \mu\tau)\geq \mathcal{O}(10^{-7})\) . In these regions,  the charged Higgs boson mass lies within the range of \(2-3\) TeV. Our results show that the LFV decays are important channels to distinguish the E331\(X_R\)  and the original economical (E331) models, which predicts suppressed LFV decay rates.
