Asymptotic nucleon form factors from current algebra and the Regge model

Current algebra identities and the Regge model are used in order to obtain the asymptotic behaviour of the electric and magnetic nucleon form factors. This is done for the scattering of an axial current on a spin-1/2 target. It is shown that the scattering amplitude can be decomposed into a set of s...
