Study and Investigation of Hard Photons Emission in Heavy Ion Collisions

摘要

This work involves hard photon rate production from quark -gluon plasma QGP interaction in heavy ion collision.Using a quantum chromodynamic model to investigate and calculation of photons rate in ???? → ?????? system due tostrength coupling, photons rate, temperature of system, flavor number and critical. The photons rate productioncomputed using the perturbative strength models for QGP interactions. The strength coupling was function oftemperature of system, flavor number and critical temperature. Its influenced by force with temperature of system, itsincreased with decreased the temperature and vice versa. The strength coupling has used to examine the confinementand deconfinement of quarks in QGP properties and influence on the photon rate production. In our approach, wecalculate the photons rate depending on the strength coupling, photons rate and temperature of system with otherfactors. The results plotted as a function of the photons energy. The photons rate was decreased with increasedtemperature and increased with decreased with strength coupling.
