Quark-Gluon Plasma (QGP) is a new state of matter expected by QCDin hot and dense state. The existence of QGP is expected in the earlyuniverse, inside of a neutron star, and relativistic high energy heavy ioncollisions. The last one is only the tool we can study on the earth.In this seminar, I will present results of experimental study for QGP at theRelativistic Heavy Ion Collider (RHIC) at BNL. While there are some probesto search and study QGP, I will talk some key measurements with a focus onthe investigation using lepton channels.
