Fermi advanced his successful theory of p-decay in 1934. It has since then undergone
development in which two general directions may be dis cerned. One has been a …

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 …

'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 …

As early as1948the great similarity in the strength of the coupling constants in beta decay,
muon decay, and muon capture had tempted several authors''to postulate a universal Fermi …

'~) R. Yang will speak to us on the" new" particles. In this talk, I shall speak only ofthe" old"
particles. To simplify thematter, the main part of this talk will be concerned with the question …

The branching ratios of various decay modes of K-meson are discussed on the basis of a
universal vector and axial-vector four-fermion interaction. The simplest and most …

The theory-of weak interactions of elementary-particles is reviewed relative to the
hypotheses of the universal rermi V--A interaction between particles and the composite …

The near equality of the effective coupling constants in the processes of beta decay, muon
decay and muon capture has led to the postulation of a Universal Fermi Interaction between …

Six-fermion weak interactions, in addition to the usual four-fermion weak interactions, may
exist. Limits on the strength of such interactions deduced from low-energy decay …
