Solar and atmospheric neutrinos: a solution with large extra dimensions

Abstract

We have studied [1] flavor neutrinos confined to our four-dimensional world coupled to one "bulk" state, i.e., a Kaluza-Klein tower. Within a minimal model, we accomodate existing experimental constraints (CHOOZ experiment, solar and atmospheric data). No direct flavor oscillations nor MWS effects are needed. An energy independent suppression is produced at large distances.
