摘要

The leptonic sector of the standard model is revisited in the light of a recent strictly covariant, generalized quantum field formalism that naturally accounts for the "maximal P-violation" effect without needing to postulate any true failure of P mirror symmetry. In full accordance with neutrino-antineutrino phenomenology, such an approach strictly predicts the nonexistence of right-handed (massless) neutrinos and left-handed (massless) antineutrinos: it spontaneously lends to a universal theory of a merely left-handed massless fermion and a merely right-handed corresponding antifermion, where such particles may now be P-symmetrically interpreted as just two pseudoscalar-charge conjugated objects being the ordinary mirror image of each other. On these grounds, a weak isospin of pseudoscalar components is introduced, which can alternately yield a double-either SU(2)(L) (leptonic) or SU(2)(R) (antileptonic)-variety of SU(2) representations, each with its own weak-hypercharge variety. Hence two equally allowable SU(2) X U(1)massless gauge schemes are covariantly built, the former including (right-handed) antileptons as SU(2)(L)-singlets and the latter including (left-handed) leptons as SU(2)(R)-sing lets. In either alternative scheme, the "charged" lepton and antilepton can but bear as yet an electric charge quite indefinite in sign: they can really be made two electric charge conjugated eigenstates (with opposite eigenvalues) only by acquiring mass and turning into Dime particles. Herein the chaged-lepton mass appearance no longer looks like just an external "accident" connected with a hypothetical coupling to a Higgs boson; it rather becomes an essential internal requirement for the generation of the leptonic electromagnetic gauge coupling. A suitable effective mechanism of mass production is shown to be provided by simply introducing a net "vacuum" Higgs isodoublet field merely including the three Goldstone freedom degrees and not including the Higgs-boson excitation: such a field still has a nonzero vacuum expectation value and still generates SSB and Weinberg mixing, though with the only further (internal) effect of giving mass to both the intermediate vector bosons and the charged lepton (antilepton). Two equivalent covariant electroweak final schemes for either leptons or antileptons are thus obtained which contain no Higgs-boson couplings and can all the same reproduce the well-established standard results. Either scheme may be said not to be P-symmetric but for the presence of the neutral weak current coupling, as a mere outcome of the mixed land not purely pseudoscalar) nature of the "electroweak" effective charge therein involved.
