The QCD analysis of the combined set for the F₃ structure function data based on the analytic approach

الأصل · EN

We apply analytic perturbation theory to the QCD analysis of the xF₃(x,Q²) structure function considering a combined set of deep inelastic scattering data presented by several collaborations, and extract values of the scale parameter LambdaQCD, the parameters of the form of the xF₃ structure function, and the x-shape of the higher twist contribution. We study the difference between the results obtained within the standard perturbative and analytic approaches in comparison with the experimental errors and state that the greatest difference occurs for large x.
