摘要：

The form factors of baryons at large momentum transfer are computed in quantum chromodynamics (QCD) to leading order in s(Q2) and m2Q2. Asymptotically, we predict Q4GMp(Q2)C[s(Q2)]2+43 and GMnGMp-23, where =11-(23)nflavor and C>0. Form factors for processes in which the baryon helicity is changed or in which the initial or final baryon has helicity greater than 1 are suppressed by factors of mQ. We also give QCD predictions for general exclusive scattering processes at large momentum transfer. © 1979 The American Physical Society.
