  2. This is not the mass-reversal transformation discussed byJ. Tiomno (Nuovo Cimento,1, 226 (1955)) which requires invariance of the total Lagrangian when a substitutionψ →γ 5 ψ,m → −m is made for all fields. In this case neutrino self-mass δm v need not vanish. In fact δm v ∞mf(m 2) and thus\(\delta m_\nu \bar \psi _\nu \psi _\nu \) does not change sign.

  3. We write all field operators with their particle symbols: thusπ(x) stands for the π-meson field,v(x) for the neutrino-field etc.
