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
![Page 11: What have we learned from Monte Carlo models? HIJING](https://reader036.vdocuments.site/reader036/viewer/2022062409/56814f81550346895dbd33fa/html5/thumbnails/11.jpg)
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
