Abstract

We compute the thermal photon production rate from a chirally asymmetric quark gluon plasma. We estimate the hard part from scattering of chiral quarks and demonstrate the cutoff independence of the total thermal photon emission rate. This is achieved by combining the hard with the soft contribution evaluated in our previous work [N. Chaudhuri et al., Phys. Rev. D 112, 094046 (2025)] using the Braaten-Pisarski method of hard thermal loop perturbation theory. It is observed that the presence of chiral imbalance leads to an overall enhancement in the emission rate of thermal photons.
