Electroweak interaction model with an undegenerate double symmetry
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. In such a model the fields of $W$ and $Z$-bosons are a superposition
of polar and axial four-vectors, and the physical vacuum, being a
condensate of
Higgs fields, does not possess a definite spatial parity. The model
naturally allows for the existence of the axial photon and its possible
nonuniversal interaction with the neutrinos of various types.
