Target mass corrections to structure functions in neutrino deep-inelastic scattering

Abstract

With the improvement of accuracy in the inclusive deep-inelastic scattering experiments, it has become apparent that comparable improvements are needed in the accuracy of the theoretical analysis tools. As well-known, extracting structure functions in the region large values of the Bjorken variable x, it is crucial to correct data by effects associated with the non-zero mass of the target. We investigate this question and demonstrate that target mass corrections to structure functions calculated by using the new approach have a correct spectral property and noticeably differ that the standard Georgi-Politzer method gives, especially for values Q2 of the order of 1 ÷ 2 GeV2 and large values of the Bjorken variable x.
