Abstract: (WSP)
Massive chiral fields, “left-handed” for fermions and “right-handed” for antifermions, are shown to be a natural prediction of a new approach to the Dirac field theory which in the zero-mass limit spontaneously yields Weyl’s two-component scheme. Such an approach gives an improved theoretical framework to the “standard model”: It accounts for (and clarifies the origin of) the “P-violation” effect, without needing any ad-hoc external prescriptions. A double-faced—either “Dirac” or “chiral” — model of a massive spin12\frac{1}{2} fermion is involved, due to the internal coexistence of two anticommuting—scalar and pseudoscalar—varieties of charges, the former being responsible for “P-conserving” processes and the latter for “P-violating” ones. The resulting scheme, besides naturally embodying the P-violation effect, leads paradoxically to a retrieval of parity symmetry itself: owing to the anticommutivity property of the above coexisting charge varieties, a chiral fermion is predicted to be the same as a mere...
