Description
The polarized proton-proton collider at RHIC provides an unique opportunity to study the spin structure of proton. In this talk, I will present recent study high-lights in longitudinal and transverse spin structure of proton at RHIC. The RHIC spin program lately executed the transversely polarized proton-nucleus collision at high energy. We observed strikingly strong atomic mass number dependence in the observed asymmetry of a forward neutron production. I will discuss about the mechanism of the asymmetry.
