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 nu(mu) --> nu(tau) or nu(mu) --> nu(sterile) 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. (C) 2000 Elsevier Science B.V.
