Thermal Axion Production at Low Temperatures: A Smooth Treatment of the QCD Phase Transition
We study thermal axion production around the confinement scale. At higher temperatures, we extend current calculations to account for the masses of heavy quarks, whereas we quantify production via hadron scattering at lower temperatures. Matching our results between the two opposite regimes provides...
