LHC/CERN experiments on high
energy nuclear physics 
RHIC/BNL the physics of QGP formation, dynamics and hadronization is studied near to the
critical quark and gluon deconfinement temperature about Tc~200 million electron volts where even nuclei melt into a "Perfect Fluid" of nearly free primordial quarks and gluons. My research today is directed toward trying to understand
the chromo-color structure of those fluids possibly involving emergent chromo magnetic monopole degrees of freedom near Tc. (see my CCNU and QM18 lectures below)

The first indication for the dicovery of a new form of quark gluon matter at RHIC was reported at CIPANP 5/21/03 The Null Control experimental results on Deuteron+Au at RHIC reported 1 , 2 on June 18, 2003 marked the birthday of the Quark Gluon Plasma (QGP) discovery at RHIC in my opinion.
The Deuterium+Au data on the absence of jet quenching in this reaction in the pT~3-10 GeV range proved that the previous observation of strong jet quenching in Au+Au (1) and the striking unquenching of back-to-back correlations in D+Au reported from the four experiments, STAR , PHENIX , PHOBOS , and BRAHMS , confirmed our predictions (Ivan Vitev, M.G, PRL89(02)) and the predictions of other colleagues. These data established that strong jet quenching effect and the mono-jet topology observed in central Au+Au reactions > must be due to quark and gluon jet energy loss in the dense QCD matter that is produced in central Au+Au reactions at 200 AGeV. An alternate hypothesis based on strong initial state gluon shadowing was ruled out in the mid rapidity kinematic range (x> 0.01).
PHENIX and STAR in 2005 confirmed our jet quenching predictions out to pT~ 20 GeV/c. The absence of suppression of direct photons provides a further control showing that only colored quark and gluon jets are quenched as we predicted via the Standard Model QCD.
Our jet tomographic analysis of the Au+Au quenching pattern indicates that the initial energy density of the QCD matter in Au+Au central reactions was about 100 times higher than in ordinary nuclei. The predictions and analysis were based on our GLV opacity expansion formalism of nonabelian energy loss. Jet quenching in high energy nuclear collisions was proposed in collaboration with Michael Pluemer and Xin-Nian Wang as a novel probe of ultra-dense QCD matter produced at RHIC and higher energies. For a (pdf format) review of our theory of jet quenching and tomography click [GVWZ_03.pdf]
The quenching pattern in Au+Au, together with the striking bulk hydrodynamic collective elliptic flow pattern prove not only that the highest density matter ever formed in the laboratory was produced at RHIC, but that it is the sought after new form of primordial Quark-Gluon-Plasma (QGP) phase of matter since 1975.
The bulk collectivity observed predicted by hydrodynamics agrees with the observed elliptic flow moments, v2(pT<2 GeV,h), when the lattice QCD equation of state is used as input. Significantly, the initial density inferred from our jet tomographic analysis is close to that infered from hydrodynamic analysis . In contrast, at lower (SPS, AGS) energies the bulk collective flow was found to be much weaker than predicted via perfect fluid hydrodynamics. The accumulated evidence on the remarkable collective flow characteristics led to the April 18, 2005 BNL announcement of the "Perfect Fluid" property of the QGP observed at RHIC.
For these and other reasons I concluded [1] that a QGP was discovered at RHIC. In collaboration with T. Hirano, we have further argued that the "perfect fluidity" discovered at RHIC is a unique experimental signature of the deconfinement of quark and gluon degrees of freedom above a temperature T>170 MeV as predicted by lattice QCD. While many details of the QGP formation, dynamics, and freezeout are not yet completely understood, the existence of this ultra-dense form of QCD matter is now established via its high opacity to penetrating jets, its remarkable bulk elliptic flow patterns, and +Au control experiments at RHIC. Essential probes such as identified heavy (charm, bottom) quarks jet observables, photon tagged jets, and multipacticle soft-hard correlations will require extensive further measurements in $p+p, p+A,$ and $A+A$. Since 2012 the discovery of collective flow correlations in high multiplicity $p+A$ at LHC and the relatively slow variation of azimuthal correlations with beam energy scans at RHIC have posed new puzzles that are currently under investigation.
