Baryon form factors

We calculate the form factors of the baryon octet in the framework of heavy baryon chiral perturbation theory. The calculated charge radius of the Sig ma(-) is in agreement with recent measurements from CERN and Fermilab. We s how that kaon loop effects can play a significant role in the neutron elect ric form factor. Furthermore, we derive generalized Caldi-Pagels relations between various charge radii which lire free of chiral loop effects. (C) 19 99 Elsevier Science B.V. All rights reserved.
