  Any of neutrinos similarly to a kind of charged lepton has a non-zero mass
responsible as well as for its Coulomb behavior. Such a neutrino can possess
both electric charge and vector dipole moment. Their form factors appear, for
example, at the polarized neutrino scattering in the field of a spinless
nucleus. We derive an equation which relates the masses to a ratio of Dirac and
Pauli form factors of each lepton and its neutrino. A new left-right
antisymmetric theory of force unification based on a gauge group $SU(2)_{L}$
$\otimes$ $SU(2)_{R}$ $\otimes$ $U(1)$ is suggested. In this theory, the
leptons and their neutrinos are united in families not only of the left-handed
$SU(2)_{L}$-doublets, but also of the right-handed $SU(2)_{R}$-doublets.
Thereby, it predicts the existence in nature of the left (right) dileptons and
paradileptons. A formation of any of them is responsible for the legality of
conservation of charge, lepton flavors and full lepton number. Therefore, each
of the earlier measured processes originated at the conservation both of summed
electric charge and of any lepton number may serve as the first confirmation of
a given theory in which the mass, charge and vector dipole moment of the
neutrino are proportional, respectively, to the mass, charge and vector dipole
moment of a lepton of the same family.
