A neutral pseudoscalar field with vanishing rest mass is introduced. We first ask for the
condition guaranteeing the vanishing rest mass, which turns out to be an invariance …

The parity-non-conserving, VA form of Fermi interaction is derived from a principle of
invariance under a continuous group of transformations, in analogy with the ordinary gauge …

The relation between the lack of renormalization and the conserved current is investigated.
Furthermore, it is proved under some conditions that we cannot construct a conserved …

Some consequences of the assumption that every interaction which exists in Nature never
allows us to determine the signs of masses of all elementary particles, are discussed. The …

The postulate of a «local connection» in a [3] charge space leads to the introduction of three
spin one fields. One of these can be identified with the electro-magnetic field and the other …

Summary The Feynman, Gell-Mann model of weak interactions is modified by the
introduction of neutral «currents», both of the strangenesss preserving (J) and strangeness …

A class of non-Abelian gauge theories of strong interactions is described, for which parity
and strangeness are automatically conserved, and for which the nonconservations of parity …

The invariance of strong interactions under G, the product of charge symmetry and charge
conjugation, has important consequences for strangeness-conserving lepton interactions …

According to Sakata's composite hypothesis of heavy particles, we assume that the
fundamental particles do not change their kind through strong interactions. A formulation of …

It has been shown that in a renormalizable gauge-invariant field-theory model, besides the
usual factorizable contribution to the parity-violating vector-meson-exchange potential there …
