NEW ELECTROWEAK FORMULATION FUNDAMENTALLY ACCOUNTING FOR THE EFFECT KNOWN AS "MAXIMAL PARITY-VIOLATION"

The electroweak scheme is wholly recast, in the framework of a relativistic quantum field formalism being a covariant fermion-antifermion extension of the usual one for massive spin-1/2 point fermions. The new formalism is able to reread the ``maximal P-violation'' effect in a way restoring P and C symmetries themselves: it provides a natural ``chiral field'' approach, which gives evidence of the existence of a pseudoscalar (extra) charge variety anticommuting with the scalar (ordinary) one and just underlying the ``maximally P-violating'' phenomenology. Its zero-mass limit leads to a strict ``chiral'' particle theory, which remodels any massless spin-1/2 fermion and corresponding antifermion as two mere pseudoscalar-charge eigenstates being the simple mirror images of each other. On such a basis, the (zero-mass) electroweak primary fermions are all redefined to be (only left-handed) ``chiral'' particles (with right- handed complements just standing for their antiparticles) and to carry at most scalar charges subjected as yet to a maximal uncertainty in sign: it is only by acquiring mass, and by gaining an extra helicity freedom degree, that they now may also manifest themselves as ``Dirac'' particles, with sharp scalar-charge eigenvalues. The fermion-mass appearance is thus made herein a dynamical condition strictly necessary to obtain actual superselected scalar-charge (and first, electric-charge) eigenstates. A pure ``internal'' mass-generating mechanism, relying only on would-be-Goldstone bosons (even to yield fermion masses) and no longer including an ``external'' Higgs contribution, is adopted accordingly. This is shown to be a self-consistent mechanism, which still maintains both renormalizability and unitarity. It involves a P-breaking in the neutral-weak-current sector (due to the Weinberg mixing) while it leaves the charged-current couplings truly P-invariant even in the presence of a (standardly parametrized) CP-violation.
