ABSTRACT: We work
on photon production through annihilation and Compton, and annihilation with
scattering (AWS) processes through a quark-gluon plasma (QGP) in high energy
nuclear collision incorporating the parametrization factors in strong coupling
value and thermal dependent quark mass obtained through a coupling value. We
find that photon yield increases with the increasing of the temperature and
dominated by early times. We also compare the influence of coupling value on
the spectrum of thermal photons. The production rate of photons is observed in
the range of low and intermediate transverse momentum. The results are compared
with other work.
