| Research Abstract |
We have developed an event selection system for PHENIX experiment at the only polarized proton-proton collider in the world. The main purpose of the project is to understand the structure of the proton, which is the fundamental constituents of the matter, which includes ourselves, from the viewpoint of the important characteristic of an elementary particle, spin. This new system has opened a new era of the proton spin-structure studies to measure the spin polarization of sea quarks directly, by means of weak boson production in polarized proton-proton collision for the first time in the world.
