An Analysis of Unpolarized Structure Function Moments in n* Excitation Region

The main goal of the present analysis is the direct evaluation of the moments of the structure function F₂, which implies numerical integration of the experimental data over x at fixed Q², in whole available Q² range. This experimental information will allow to extract the contribution of the higher twists related to multiparton correlation effects. Moreover the comparison with theoretical predictions either based on first-principle calculations, like lattice QCD simulations, or obtained from models of the nucleon structure may represent an important test of the nonperturbative QCD regime.
