Sažetak
All neutrinos have a non-zero mass and regardless of whether a neutrino is of the Dirac or Majorana type, it can possess both anapole and electric dipole moments. Between the corresponding form factors there appears a connection, for example, for neutrino scattering on spinless nuclei. We discuss a theory in which a mass consists of vector and axial-vector components responsible for separation of leptonic current into the vector and axial-vector parts of the same charge or dipole moment. Such a model can explain the absence of truly neutral neutrino vector interactions and the availability of an axial-vector structure of a Majorana mass. Thereby, it relates the two neutrinos of different nature. We derive an equation which relates the masses to a ratio of the anapole and electric dipole form factors of any charged lepton and its neutrino as a consequence of their unification in families of doublets and singlets. This testifies in favour of the existence of the left (right) dileptons and paradileptons of the axial-vector currents. Each of them answers to conservation of an axial-vector charge and any lepton flavour. Therefore, an axial-vector mass, anapole and electric dipole moment of the neutrino become proportional, respectively, to an axial-vector mass, anapole and electric dipole moment of a particle of the same family.
