On fermion mass hierarchy with extra dimensions
Abstract
Recently, various phenomenological implications of the existence of extra space-time dimensions have been investigated. In this paper, we try to construct a model with realistic fermion mass hierarchy with (large) extra dimensions beyond the usual four dimensions. In which model, it is assumed that some matter fields live in the bulk and the others are confined in our four dimensional wall. It can naturally reproduce the quark and lepton mass hierarchy and mixing angles without any symmetry arguments. We also discuss some possibilities of obtaining suitable neutrino masses and mixings for the solar and atmospheric neutrino problems.Keywords
