    • Abstract

       

      We analyse the proton electromagnetic form factor ratioR(Q2) =QF2(Q2)/F1(Q2) as a function of momentum transferQ2 within perturbative QCD. We find that the prediction for (R(Q2) at large momentum transferQ depends on the exclusive quark wave functions, which are unknown. For a wide range of wave functions we find thatQF2F1 ∼ const. at large momentum transfer, which is in agreement with recent JLAB data.
