Dark Grand Unification in the axiverse: decaying axion dark matter and spontaneous baryogenesis
Abstract The quantum chromodynamics axion with a decay constant near the Grand Unification (GUT) scale has an ultralight mass near a neV. We show, however, that axion-like particles with masses near the keV–PeV range with GUT-scale decay constants are also well...
