Connection between the elastic GEp/GMp and P-->Delta form factors

It is suggested that the falloff in Q2 of the P-->Delta magnetic form factor G*M is related to the recently observed falloff of the elastic electric form factor G(Ep)/G(Mp). Calculation is carried out in the framework of a generalized parton distribution model whose parameters are determined by fitting the elastic form factors F(1p) and F(2p) and isospin symmetry. When applied to the P-->Delta transition with no additional parameters, the shape of G*M is found to exhibit the requisite falloff with Q2.
