摘要：

Motivated by existing and recent data on possible neutrino oscillations, we propose a model of four light neutrinos (nu(e), nu(mu), nu(tau), and a singlet nu(S)) with a pattern of masses and mixing derivable from a discrete Z(5) symmetry and the seesaw mechanism. Atmospheric neutrino oscillations occur between nu(mu) and nu(tau) as pseudo Dirac partners, whereas solar neutrino oscillations occur between nu(e) and nu(mu) to be account for the recent observation of the LSND (Liquid Scintillator Neutrino Detector) experiment.
