The axial vector current in beta decay
M Gell-Mann, M Lévy - Il Nuovo Cimento (1955-1965), 1960 - Springer
In order to derive in a convincing manner the formula of Goldberger and Treiman for the rate
of charged pion decay, we consider the possibility that the divergence of the axial vector …

J Bernstein, M Gell-Mann, L Michel - Il Nuovo Cimento (1955-1965), 1960 - Springer
The models of the axial vector current discussed by Gell-Mann and Lévy are examined
further. Generalized Ward identities are derived for the axial vector weak vertex. It is then …

Notes on the static parity non-conserving internucleon potential
G Barton - Il Nuovo Cimento (1955-1965), 1961 - Springer
If the weak Lagrangian density ℒ consists of self-interacting charged currents, the inclusion
into these of a term linear in the pion field leads to a static parity non-conserving …

Mesonic enhancement of the weak axial-vector current evaluated from β decay in the lead region
EK Warburton - Physical review letters, 1991 - APS
A shell-model study is made of first-forbidden β decay in A= 205–212 nuclei. A least-squares
fit for eighteen ΔJ= 0 and 1 decays gave a scaling factor for the rank-one contributions of …

Sum Rules for the Axial-Vector Coupling-Constant Renormalization in Decay
SL Adler - Physical Review, 1965 - APS
Starting from the axial-vector current algebra suggested by Gell-Mann and the hypothesis of
a partially conserved axial-vector current, we derive a sum rule relating 1− g A− 2 to off-mass …
