The general direct coupling between four fermions is studied. It is a linear combination of the
five invariants used in β-decay theory. Altering the order of the particles in the Hamiltonian …

The representation of Fermi particles by two-component Pauli spinors satisfying a second
order differential equation and the suggestion that in β decay these spinors act without …

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 …

'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 …

Assuming the symmetric coupling scheme proposed by Wheeler and Tiomno, and others,
we have calculated the ratio of the decay rate π− meson→ electron+ neutrino to the decay …

The purpose of this communication is to present a coherent summary of the author's
theoreticaI proposals [1] concerning the new unstable particles. i Section 2 is devoted to …

The measure of the asymmetry fS as a function of y gives t'a and tP. The magnitude of the
parameter f, which isthe degree of polarization of the p meson, depends on the …

The polarization of electrons in muon decay is studied in the case of the four-component
neutrino theory with general parity-nonconserving interactions. The spectrum for each of the …

FIG. l. In addition to the three meson nonets, with J= 0, 1, and 2+, which are discussed in the
text, 16 possible candidates for J+= 1 assignments are shown. These are A~(1090), B …

Some properties are discussed of the θ 0, a heavy boson that is known to decay by the
process θ 0→ π++ π−. According to certain schemes proposed for the interpretation of …
