Nucleon and Δ electromagnetic form factors

Abstract

The unitary and analytic model for nucleons works very well. The model for spin 1 2 + baryons can predict static parameters for Λ, Σ + , Σ 0 , Σ − , Ξ, Ξ − . We prepared the scheme how to construct the model also for ∆ nucleon resonance. It was used to describe transition form factor G * M and the experimentally measured ratio R SM with the help of relations for magnetic dipole transition and charge quadrupole form factors.
