Results are presented of a perturbative QCD analysis of heavy baryon form factors to leading order in (Y s including all higher twist quark mass effects. A dip in the total cross section for the efe- pair production of some higher genera- tion nucleons is predicted. The results are consistent with the definition of charge form factors at zero momentum transfer and reproduce the well known anomalous magnetic moments of nucleons. These considerations resolve a sign ambiguity in previous leading twist analyses of the hard scattering contribution to the proton magnetic form factor.
