Soft-contribution to thermal photon emission from chiral QCD medium

Year: 2025

Type: article

Abstract: We evaluate the thermal photon emission rate from a chirally asymmetric quark gluon plasma using the hard thermal loop approximation. The quasiparticle and plasmino modes prevalent at finite temperature split into L and R -modes in the presence of chiral imbalance and are found to disperse differently acquiring different thermal masses. The soft contribution to the thermal photon emission rate obtained from the retarded self-energy is found to contain additional terms proportional to the square of the quark and chiral chemical potentials which is found to cause an enhancement to thermal photon emission in the presence of chiral imbalance.
