Titile: Nucleon spin structure study at RHIC-STAR

Abstract:The STAR experiment at RHIC (Relativistic Heavy Ion Collider) at Brookhaven

National Laboratory is running polarized proton-porton collisions at sqrt s=200 GeV and 500 GeV. The main goal of the RHIC spin physics program aims to gain a deeper insight into the spin structure of the nucleon.

We will give an overview of recent spin results from STAR experiment, in particular the study of gluon polarization via jet/hadron production and the sea quark polarization via W boson production in longitudinally polarized proton-proton collisions at RHIC.
