The form factor of the transition gamma gamma * pi^0
N. Nasrallah
A simple method is used to extrapolate the form factor for the process gamma* gamma *--->pi^0 when two virtual photons produce a pi ^0 from the region of large spacelike photon vir…

Delta I = 1/2 enhancement and the Glashow-Schnitzer-Weinberg sum rule
N. F. Nasrallah, K. Schilcher
In 1967 Glashow, Schnitzer and Weinberg derived a sum rule in the soft-pion and soft kaon limit relating the Delta I=1/2 non-leptonic K->2pi amplitude to integrals over strange and…
