  Abstract:
We present our new determination of polarized PDFs of the nucleon at NLO accuracy performing a QCD fit on the global set of newest com- bined inclusive deep inelastic scattering (DIS) and the semi-inclusive po- larized deep inelastic scattering (SIDIS) data. Considering SIDIS data, which comes from the hadronization of polarized DIS process, helps us to break SU(2) and SU(3) symmetry and light sea-quark decomposition hap- pens. Our results are compared with the most precise theoretical models obtained by recent analyses.
