Analytic Perturbation Theory: Target Mass Corrections to Nucleon Structure Functions

Abstract

For accounting of target mass contributions to unpolarized nucleon structure functions in the deep-inelastic scattering, we suggest to use a new approach which follows from the use of the ideas of the analytic perturbation theory. It is shown that this approach eliminates a known problem, which arises in the limit as the Bjorken variable x → 1. We have demonstrated that the target mass corrections to the structure functions calculated by using this new approach can be noticeably differ from the standard Georgi–Polizer approach result.
