Neutrino oscillations and rare processes in models with a small extra dimension

We discuss Dirac neutrino masses and mixings in a scenario where both the standard model fermions and right handed neutrinos are bulk fields in a nonfactorizable geometry in five dimensions. We show how the atmospheric the solar neutrino anomalies can be satisfactorily resolved, and in particular how bimaximal mixing is realized. We also consider rare processes such as neutronantineutron oscillations and μ → e+γ, which may occur at an observable rate. [email protected] [email protected]
