Quark-GluonPlasma Phase Diagrame
Quark-Gluon Plasma High-energy nuclear collisions will compress and heat the heavy nuclei so much that their individual protons and neutrons overlap and lots of pions arise, creating the Quark-Gluon Plasma (QGP) QGP is thought to have existed ten millionths of second after the Big Bang; creating the primordial matter of universe in the laboratory, Little Bang.

Monte Carlo Calculations in case of Heavy ion collision HIJING Model Can surprise you! Why?
Today's Monte Carlo models • Monte Carlo models: • HIJING • PYTHIA/FRITIOF • NEXUS, VENUS • DPM
Assumption of HIJING Model HIJING Model: Heavy ion Jet international Generator Model. Glauber MC Model: Glauber theory is based on the assumptions of 1- A characteristic nucleon-nucleon (nn) cross section 2-Straight line trajectories of the colliding nucleons
V2 Number of Charged HIJING Model for Au+Au collision at 60 GeV/n
V2 Number of Charged HIJING Model for Au+Au collision at 130 GeV/n
Conclusion • V2 Elliptical flow, Rabidity Distribution, Npart and Ncoll predicted by the HIJING Monte Carlo for Au+Au and D+Au collision calculated.
Feature of the future ComparisonbetweenHIJING Monte Carlo calculation and CERN data can be done.
