Equality of β-decay coupling constants C′ A/CA= C′ V/CV= 1, implying VA interaction, is
less verified than commonly assumed. Deducing limits 0.52< C′ V/CV< 1.93 and 0.82< C …

An attempt is made to determine the best values of the coupling constant ratios CACV,
CSCV, CTCV, C′ VCV, C′ ACV, C′ SCV, C′ TCV from all relevant measurements on …

1. INTRODUCTION iHE discovery of parity nonconservation in 1956 is one of the most
surprising occurrences in the history of physics. The experiment of Wu (Fl) with polarized …

The failure of the ξ approximation in which only the first nonvanishing term is kept in the
expansion in descending powers of the Coulomb energy factor is due to either the …

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 …

In 1934, Enrico Fermi, then a professor of theoretical physics at the University of Rome, Italy,
proposed his clear and simple description of [3 decay. He assumed the existence of the …

We obtain three independent values of the effective vector coupling constant for nuclear β-
decay by using various pieces of experimental data (the neutron life-time and the β-decay …

The semileptonic B decay, B 0→ π+ l− v, is studied in a nonrelativistic picture by treating the
pion correctly as a quasi-Nambu-Goldstone boson. The branching ratio is much larger than …
