Abstract

In the framework of a Kaluza-klein type theory with the Standard Model fields localized on a 4-dimensional section while gravity propagates in a full 4 + δ-dimensional space-time, we examine a mechanism of naturally small neutrino mass generation through couplings of the Standard Model singlet fermion(s) living also in the full space-time. A numerical study is carried out on the charged current universality constraint from the ratio of pion decay partial widths. The bounds obtained on the fundamental mass scale could be stringent.
