QCD axion dark matter in the dark dimension

Abstract The recently proposed dark dimension scenario reveals that axions can be localized on the Standard Model brane, thereby predicting the quantum chromodynamics (QCD) axion decay constant from the Weak Gravity Conjecture: f a ≲ M 5 ~ 109 – 1010 GeV, where M 5 is the five-dimensional Planck mas...
