Axion misalignment driven to the bottom

Abstract Several theoretical motivations point to ultralight QCD axions with large decay constants f a ≃ O 10 16 − 10 17 GeV $$ {f}_a\simeq \mathcal{O}\left({10}^{16}-{10}^{17}\right)\ \mathrm{GeV} $$ , to which experimental proposals are dedicated. This regime is known to face the problem of overpr...
