When the [phi]-particle's mass is zero ([m.sub.0] = 0), the Tau-neutrino is in its natural state of being an Tau-neutrino and when the mass of the [phi]-particle is negative (-[m.sub.0]), the Tau-neutrino enters the Electron-neutrino state and likewise, when mass of the [phi]-particle is positive (+[m.sub.0]), Muon-neutrino enters the [mu]-neutrino state.
The upper bounds of the neutrino mass are about 4.7 eV for the electron-neutrino, 170 keV for the muon-neutrino, and 18 MeV for the tauon-neutrino.
