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 …

An attempt is made to construct a theory of all weak processes from a single invariance
principle. The requirement that the weak interaction Hamiltonian be invariant under the …

It is assumed that the results of relativistic quantum theories should be invariant under the
change in sign of the mass term in the Dirac Equation. The consequences of this principle …

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 …

On the basis of the hypothesis that the same form of interaction acts among any spin-½
particles, it is interesting to apply the interaction law found for β decay to the muon …

With the aim to investigate the possibility of reducing the complicated interactions between
various sorts of elementary particles to some kind of interactions which have certain primary …

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

'HE idea of a universal Fermi interaction has received some attention recently, partly as a
result of various proposed symmetry principles' which restrict the form of the 4-fermion …
