Target mass corrections to nucleon spin structure functions are analyzed. Our results show that the corrections are important to the structure functions in a large x region. Moreover, they play a remarkable role to the local quark-hadron duality of the nucleon spin structure functions in three indiv

β¦ Synopsis
With recent advances 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 for effects associated with the non-zero mass of the target. We present here an updated, more accurate, version of our calculations based on the Jacobi polynomial expansion method on performing a global fit to the existing data by imposing target mass correction effects. The effects of these corrections are studied and polarized structure functions with and without them are compared.
