Baryon form factors in chiral perturbation theory
Bastian Kubis, Ulf-G. Meißner
Abstract
We analyze the electromagnetic form factors of the ground state baryon octet to fourth order in relativistic baryon chiral perturbation theory. Predictions for the Σ- charge radius and the Λ-Σ0 transition moment are found to be in excellent agreement with the available experimental information. Furthermore, the convergence behavior of the hyperon charge radii is shown to be more than satisfactory.
