| Abstract | For deuteron's electromagnetic form factors, perturbative QCD (pQCD) predicts that G(00)(+) becomes the dominate helicity amplitude and G(+0)(+), and G(+-)(+) are suppressed by factors Lambda QCD/Q and Lambda (2)(QCD)/Q(2) at large Q(2) respectively. We try to discuss the higher-order corrections beyond the pQCD asymptotic predictions by interpolating an analytical form to the intermediate energy region. From fitting the data, our results show that the helicity-zero to zero matrix element G(00)(+) dominates the gross structure function A(Q(2)) in both the large and intermediate energy regions. It is a good approximation for G(+-)(+) to ignore the higher-order contributions and the higher-order corrections to G(+0)(+) should be taken into account due to sizeable contributions in the intermediate energy region. |
