New ZEUS data are added into the NLO QCD analysis of the ZEUS-JETS PDF fit.The addition of high-$Q^2$ NC and CC $e^-p$ inclusive cross-section dataimproves the determination of the $u$-valence quark at high $x$. The additionof high-$Q^2$ CC $e^+p$ inclusive cross-section data improves the determinationof the $d$-valence quark at high $x$. The addition of lower-$Q^2$ NC $e^+p$inclusive cross-section data, run at three different proton beam energies,improves the determination of the sea and gluon PDFs at small $x$. The new PDFfit is called the ZEUS09 PDF fit.

A QCD analysis of ZEUS data including DIS inclusive cross sections with longitudinally polarised leptons and data run at lower proton beam energies.
