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.
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)

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
HIJING Model for Au+Au collision at 60 GeV/n
HIJING Model for Au+Au collision at 130 GeV/n
• V2 Elliptical flow, Rabidity Distribution, Npart and Ncoll predicted by the HIJING Monte Carlo for Au+Au and D+Au collision calculated.
ConclusionConclusion
Comparison between HIJING Monte
Carlo calculation and CERN data can be done.
