Abstract

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.
