Abstract
The initial P-invariance of the electroweak
interaction Lagrangian together with the low-energy results of the
Weinberg-Salam model is provided by a local secondary symmetry.
Among the transformation parameters of this symmetry there are
both scalars, and pseudo-scalars with respect to the orthochronous
Lorentz group. Such symmetry does admissible existence of a light
(massless) axial gauge boson and its possible nonuniversal
interaction with the leptons of various types.
Key words:
double symmetry; electroweak interactions; light axial gauge boson.
