Baryon form factors in chiral perturbation theory.

We analyze the electromagnetic form factors of the ground state baryon octet to fourth order in relativistic baryon chiral perturbation theory. Predictions for the $\Sigma^-$ charge radius and the $\Lambda$– $\Sigma^0$ 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. [ABSTRACT FROM AUTHOR]
