Abstract
Lepton scattering of nucleon targets (DIS experiment) plays an essential role in the investigation of proton as a composite particle which consists of quarks and gluons. With the recent advances made in the precision of inclusive lepton-nuclear scattering experiments, it has become apparent that comparable improvements are needed in the accuracy of the theoretical analysis tools. In particular, when extracting parton distribution functions in the large-x region, it is crucial to correct the data by the effects associated with the non-zero mass of the target. In this paper, we present the effect of target mass corrections (TMCs) on the neutron and deuteron spin structure functions in the NLO QCD approximation.
