Abstract
For deuteron's electromagnetic form factors, perturbative QCD (pQCD) predicts that becomes the dominate helicity amplitude and and are suppressed by factors and at large 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 dominates the gross structure function in both the large and intermediate energy regions. It is a good approximation for to ignore the higher-order contributions and the higher-order corrections to should be taken into account due to sizeable contributions in the intermediate energy region.
