Abstract
The spin structure of proton has been a long-standing open question for the last decades. Polarized DIS and SIDIS experiments have been the Explorer of the field and providing us the knowledge the part of substructure of the proton spin by its subcomponents. In contrast to well-measured valence quark contribution to the proton spin, polarization of gluons and sea quarks still remain with a large uncertainty. PHENIX experiment has been providing various asymmetry data to introduce new constraints to the proton spin structure, particularly gluon and sea quark polarization in proton spin using the world highest-energy polarized protonproton collider, RHIC. In this report, the latest gluon polarization measurements in PHENIX through various observables are presented. Also preliminary results of W-boson production to measure the sea quark polarization in both central and forward rapidity are presented.
