Neutrino oscillations and large extra dimensions
Abstract
Assuming that right-handed neutrinos exist and propagate in some large extra dimensions, we attempt to give a comprehensive description of the phenomenology of neutrino oscillations. A few alternative explanations of the atmospheric neutrino anomaly emerge, different from the standard nuMu --> nuTau or nuMu --> nuSterile interpretations. Constraints from nucleosynthesis and supernova 1987a are discussed. The constraints from SN1987a indicates a maximum radius of any extra dimension of about 1 Angstrom.

12 pages, 5 figures. Version 2: misprints fixed, ref.s added, conclusions modified: at least in minimal models the maximal radius of large extra dimensions where right-handed neutrinos can propagate must be smaller than an atom in order to satisfy bounds from the 1987 supernova
