If axions exist, thermal axions are in equilibrium at high temperatures and freeze out at a temperature which depends on their coupling.
If the freezeout temperature is at or below the QCD crossover temperature range, thermal axions may be detectable in the cosmic radiation budget.
But evaluating the thermal axion-QGP coupling requires nonperturbative tools.
We show how to use lattice...
