We study the role of running coupling and the effect of variation of the thermal quark mass on contribution of the collinear bremsstrahlung and annihilation to photon emission in AA collisions in a scheme similar to that used in our previous jet quenching analyses. We find that for a scenario with the thermal quark mass mq ∼ 50−100 MeV contribution of the higher order collinear processes summed with the 2 → 2 processes can explain a considerable part (∼50%) of the experimental photon spectrum at kT ∼ 2–3 GeV for Au+Au collisions at \(\sqrt s \)= 0.2 TeV. However, for mq = 300 MeV and for the thermal quark mass predicted by the HTL scheme the theoretical predictions underestimate considerably the experimental spectrum.
