摘要: We investigate a simple statistical model of quark-gluon plasma (QGP) formation. In the model, we use phenomenological parameter which enhances growth quark droplet formation and also stabilizes QGP droplet. Then, study direct photon radiation through annihilation Compton processes from these stabilized incorporating parametrized momentum factor in mass. The production rate thermal is found to be dominated low transverse momentum increases little comparison recent development other theoretical experimental works.
