EFFECT OF EVOLUTION OF DIRECT PH OTONS ON THE VISCOSITY OF QUARK GLUON PLASMA

The quark - gluon plasma at the stage of thermodynamic equilibrium is reviewed. The quark hadron phase transition and the color superconducting phases of quark - gluon matter with the help of phase diagram are discussed. The lattice QCD results on the order of the phase transition of QGP . We discuss some aspects of atomic Fermi gas in the u nitary limit in the first order transition. We consider the equation of state and the critical temperature for pair condensation. The strongly interacting phase transition (Quark - Hadron phase transition) also discussed.
