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...

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 suitable invariant scalar amplitudes, free of kinematical singularities, for which a pure Regge model can be safely assumed in both s and {Mathematical expression} channels. In this way, the relevant amplitudes furnish an asymptotic expression for the nucleon form factors, whose behaviour for large t is {Mathematical expression}, where α(s) and {Mathematical expression} are the trajectories exchanged in the baryonic channels, M the nucleon mass and n1, n2 odd integer numbers. © 1971 Società Italiana di Fisica. |
