| Abstract: | We analyse the proton electromagnetic form factor ratioR(Q 2 ) =QF 2 (Q 2 )/F 1 (Q 2 ) as a function of momentum transferQ 2 within perturbative QCD. We find that the prediction for (R(Q 2 ) at large momentum transferQ depends on the exclusive quark wave functions, which are unknown. For a wide range of wave functions we find thatQF 2 F 1 ～ const. at large momentum transfer, which is in agreement with recent JLAB data. |
