The Role of Target Mass Corrections in the Polarized Spin Structure Functions of Neutron and Deuteron

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.
