摘要
Among the 27(+2) free parameters in Standard Model(SM) with massive neutrinos, 21(+2) out of them are related to the fermion masses. And most of them have been well measured in the past 50 years. Yet, we have no satisfactory understanding of the origin of flavor. However, models involve extra dimension(s) provide a new framework for understanding the hierarchical pattern of the SM Yukawa couplings. We are particularly interested in the neutrino models in higher dimension which alleviate some theoretical problems in their 4D versions. In this talk, some general features of the charged lepton flavor violating (LFV) processes in the higher dimensional neutrino models is illustrated by a simple 5D split fermion model. © 2013 Elsevier B.V.
