Thermal Axions: Production Mechanisms and Cosmological Signals

Thermal Axions: Production Mechanisms and Cosmological Signals

Scattering and decay processes of thermal bath particles in the early universe can dump relativistic axions in the primordial plasma. If produced with a significant abundance, their presence can leave observable signatures in cosmological observables probing both the early and the late universe.We...
