Thermal production of astrophobic axions
Abstract Hot axions are produced in the early Universe via their interactions with Standard Model particles, contributing to dark radiation commonly parameterized as ∆N eff. In standard QCD axion benchmark models, this contribution to ∆N eff is negligible after taking into account astrophysical limi...
