Abstract
We perform a complete and systematic calculation of the octet-baryon form factors within the fully covariant approach of chiral perturbation theory at . We use the extended on-mass shell renormalization scheme and include explicitly the vector mesons and the spin- decuplet intermediate states. Comparing these predictions with data including magnetic moments, charges, and magnetic radii, we determine the unknown low-energy constants and give predictions for yet unmeasured observables, such as the magnetic moment of the and the charge and magnetic radii of the hyperons.
