A minimal model with large extra dimensions to fit the neutrino data
Abstract
The existence of large extra dimensions enables to explain very simply the various neutrino suppression data. The flavour neutrinos, confined on the brane, are coupled to a "bulk" neutrino state, which is seen as an infinite tower of Kaluza-Klein states from the 4-dimensional point of view. The oscillation of flavour neutrinos into these states can lead to a global and sizable energy-independent suppression at large distances, which can be related to the solar neutrino puzzle.
