High Energy Physics - Phenomenology 2017-08-23 v1 High Energy Physics - Experiment

Abstract

Different methods to extract the polarized parton densities from the world polarized DIS data are considered. The higher twist corrections hN(x)/Q2h^N(x)/Q^2 to the spin dependent proton and neutron g1g_1 structure functions are found to be non-negligible and important in the QCD analysis of the present experimental data. Their role in determining the polarized parton densities in the framework of the different approaches is discussed.
