摘要

The radiative decays,π± → l±νγ and K± → l±νγ,with l standing for an e or a μ,and γ for a real or virtual photon (e+e-pair),provide a powerful tool to investigate the hadronic structure of pions and kaons.The structuredependent part SDi of the amplitude describes the emission of photons from virtual hadronic states,and is parametrized in terms of form factors V,A,(vector,axial vector),in the standard description [1,2,3,4].
