The effects of non-universal extra dimensions on the radiative lepton   flavor decays \mu\to e\gamma and \tau\to \mu\gamma in the two Higgs doublet   model
  We study the effect of non-universal extra dimensions on the branching ratios of the lepton flavor violating processes \mu\to e\gamma and \tau\to \mu\gamma in the general two Higgs doublet model. We observe that these effects are small for a single extra dimension, however, in the case of two extra dimensions there is a considerable enhancement in the additional contributions.
