We estimate the charged lepton electric dipole moments and the branching ratios of radiative lepton flavor violating decays in the framework of the two Higgs doublet model with the inclusion of two extra dimensions. Here, we consider that the new Higgs doublet is accessible to one of the extra dimensions with a Gaussian profile and the fermions are accessible to the other extra dimension with uniform zero-mode profile. We observe that the numerical values of the physical quantities studied enhance with the additional effects due to the extra dimensions and they are sensitive to the new Higgs localization.

We study the branching ratios of the lepton flavor violating processes μ→eγ, τ→eγ and τ→μγ in the split fermion scenario, in the framework of the two-Higgs doublet model. We observe that the branching ratios are relatively more sensitive to the compactification scale and the Gaussian widths of the leptons in the extra dimensions, for two extra dimensions and especially for the τ→μγ decay.

We study [Formula: see text], i = e, μ, τ decays in the two-Higgs doublet model, with the inclusion of one and two spatial non-universal extra dimensions. We observe that the branching ratio is sensitive to two extra dimensions in contrary to a single extra dimension.

We study the lepton-flavor-violating processes of τ- → μ-PP decays with PP = K+K-, [Formula: see text], π+π-, π0π0 in the framework of two-Higgs-doublet model III by virtue of the chiral perturbation theory. In this model, only three neutral Higgs bosons contribute to these decays. With the current experimental constraints, we show that (a) the contributions of the |λuu(dd)| term are very small for these four decays; (b) we get the correlation between |λss| and |λτμ|; for |λτμ| ~ 10–400, one has |λss| ~ 40–1; (c) in the existing model parameter space, Br (τ- → μ- K+K-) could reach the order of [Formula: see text], but Br (τ → μ-π+π-/π0π0) are too small to be observed.
