We study bulk fermion fields in the localized gravity model with non-factorizable metric recently proposed by Randall and Sundrum, and Gogberashvili. In addition to a tower of weak-scale Kaluza–Klein states we find a zero mode for any value of the fundamental fermion mass. If the fermion mass is larger than half the curvature of the compact dimension, the zero mode can be localized on the “hidden” 3-brane in the Randall–Sundrum model. Identifying this mode with a right-handed neutrino provides… Expand

Fermion Masses, Mixings and Proton Decay in a Randall-Sundrum Model
We consider a Randall–Sundrum model in which the Standard Model fermions and gauge bosons correspond to bulk fields. We show how the observed charged fermion masses and CKM mixings can be explained,Expand
Solutions to large B and L breaking in the Randall–Sundrum model
Abstract The stability of proton and neutrino masses are discussed in the Randall–Sundrum model. We show that relevant operators should be suppressed, if the hierarchical Yukawa matrices areExpand
Top quark Kaluza-Klein mode mixing in the Randall-Sundrum bulk standard model and constraint from delta rho
The Randall-Sundrum (RS) scenario with all the standard model (SM) fermions and gauge bosons in the bulk is phenomenologically studied. Even though the simple assumption of universal bulk fermionExpand
Majorana neutrinos with split fermions in extra dimensions

Planck scale lepton number violation is an interesting and natural possibility to explain nonzero neutrino masses. We consider such operators in the context of Randall-Sundrum (RS1) scenarios.Expand

We consider the possibility of the Higgs mechanism in the bulk in a generalized Randall-Sundrum model, where a nonvanishing cosmological constant is induced on the visible brane. This scenario hasExpand
