Performing a combined QCD fit on the global sets of latest inclusive and the semi-inclusive polarized deep inelastic scattering data, we are able to extract new polarized parton distribution functions (PPDFs) at the input scale $Q_{0}^2=1$ GeV$^2$. Particulary, we have calculated PPDFs considering light sea-quark decomposition and the results are compared with the experimental data and the most precise theoretical ","authors_text":"Ali N.
