A Stetz, J Carroll, D Ortendahl, V Perez-Mendez, G Igo… - Nuclear Physics B, 1978 - Elsevier
The branching ratio for the decay π→ eνγ has been measured in a counter experiment in
which the e+ was detected in a magnetic spectrometer and the γ-ray in a lead-glass …

Unique determination of the form-factor ratio in radiative pion decay

LE Piilonen, RD Bolton, MD Cooper, JS Frank… - Physical Review Letters, 1986 - APS
A new experiment studying radiative pion decay, π+→ e+ ν e γ has been performed with the

Rare decay modes of the neutral pion

A Pich, J Bernabéu - Zeitschrift für Physik C Particles and Fields, 1984 - Springer
The slope of the form factor for π 0→ e+ e-γ and the real part of the amplitude for π 0→ e+ e-

The QCD non-perturbative contribution to the axial form factor in radiative pion decay

NF Nasrallah, NA Papadopoulos, K Schilcher - Physics Letters B, 1982 - Elsevier
We show that QCD non-perturbative terms à la Shifman-Vainshtein-Zakharov are crucial for
understanding the radiative pion decay. We obtain for the axial-vector form factor γ= 0.0±0.3 …

Low-Energy Theorem for Pion Photoproduction from the Hypothesis of Partially Conserved Axial-Vector Current

GW Gaffney - Physical Review, 1967 - APS
By using gauge invariance and the hypothesis of partially conserved axial-vector current, the
pion-photoproduction amplitude at threshold is calculated to all orders in strong interactions …

Form factors in the radiative pion decay

V Mateu, J Portolés - The European Physical Journal C, 2007 - Springer
We perform an analysis of the form factors that rule the structure-dependent amplitude in
radiative pion decay. The resonance contributions to π→ eν e γ decays are computed …

Further Analysis of the Decay

SG Brown, SA Bludman - Physical Review, 1964 - APS
We have recalculated the structure-dependent part of the decay π→ e+ ν+ γ, using the
conserved vector current hypothesis, in order to derive information on the axial-vector …
