We study the leading order processes for photon production using a phenomenological model of quark-gluon plasma (QGP) in relativistic heavy-ion collisions incorporating the parametrization factors in thermal dependent quark mass. The measurement of photon emission provides valuable insights into the early conditions of QGP. The production rate is observed in the low and intermediate range of energy and transverse momentum. The photon yield is found to increase marginally with the effect of thermal dependent quark mass. The results are little enhanced and in good agreement with other work.
