Neutrino suppression and extra dimensions: A minimal model

Abstract

We study flavor neutrinos confined to our four-dimensional world coupled to one ``bulk'' state, i.e., a Kaluza-Klein tower. We discuss the spatial development of the neutrino disappearance, the possibility of resurgence, and the effective flavor transitions induced in this mechanism. We show that even a simple model can produce an energy independent suppression at large distances, and relate this to experimental data.
