Discovery of Quark Gluon Plasma at RHIC

Recent experimental results from Relativistic Heavy Ion Collider (RHIC) have shown the evidence of a new state of matter at high energy density. Physicists believe that the new state of matter is "Quark Gluon Plasma"(QGP) that they have been seeking for long time. This paper will survey both theoretical and experimental studies on QGP.

The quark-gluon plasma at RHIC

I present a theory-guided review of RHIC data, arguing that they provide strong evidence for formation of a thermalized quark-gluon plasma at RHIC. Strong radial flow reflects high thermal pressure in the reaction zone. Large elliptic flow proves that the pressure builds up quickly and the system thermalizes on a very short time scale of < 1 fm/c. The observed hadron yields are consistent with ...

Heavy-Quark Probes of the Quark-Gluon Plasma at RHIC

Thermalization and collective flow of charm (c) and bottom (b) quarks in ultra-relativistic heavyion collisions are evaluated based on elastic parton rescattering in an expanding quark-gluon plasma (QGP). We show that resonant interactions in a strongly interacting QGP (sQGP), as well as parton coalescence, can play an essential role in the interpretation of recent data from the Relativistic He...

Quark-Gluon Plasma Signatures

Aspects of quark-gluon plasma signatures that can be measured by CMS are discussed. First the initial conditions of the system from minijet production are introduced, including shadowing effects. Color screening of the Upsilon family is then presented, followed by energy loss effects on charm and bottom hadrons, high pT jets and global observables. ∗) This work was supported in part by the Dire...
