Charm Quark Evolution in Heavy Ion Collisions

This paper investigates the behavior of charm quarks within the extreme conditions created in heavy ion collisions. It uses a quasiparticle model to simulate the interactions of quarks and gluons in a hot, dense medium. The study focuses on the production rate and abundance of charm quarks, comparing results in different medium formulations (perfect fluid, viscous medium) and quark flavor scenarios. The findings are relevant to understanding the properties of the quark-gluon plasma.

• •The study uses a quasiparticle model to simulate charm quark behavior in hot QCD matter.
• •Charm production rate is found to decrease across different medium formulations.
• •Charm quark number is approximately conserved, consistent with experimental evidence.
