Exceptional and non-exceptional contributions to the radiative \pi decay

Abstract

We have studied the spin-one resonance dominated form factors governing the radiative decay of the \pi, within the framework of resonance chiral theory. We obtain predictions for their value at zero momentum transfer and also a description of their q^2 dependence.
