摘要：

We construct the SM with the fermions in multiplets of Majorana spinors and define a space-inversion symmetry (parity) conserved by the electroweak and strong interactions. A non-trivial Lie algebra involving P, T, SU(2)×U(1)×SU(3) and the Poincaré group is derived. In a Higgs mechanism with two scalar doublets, universality and invariance of P and T imply natural flavor conservation. © 1990.
