We propose a minimal realization of the Peccei-Quinn mechanism in a realistic SU(5) model, where the
axion mass is directly connected to the grand unification scale. Accounting for constraints from proton
decay, collider searches and gauge coupling unification, we predict the axion mass ma ∈ ½4.8; 6.6 neV.
The upper bound relaxes to ma < 330 neV for a tuned flavor structure of the proton decay operators. The
predicted mass window will be complementarily probed by the axion dark matter experiments
ABRACADABRA and CASPER-Electric, which could provide indirect evidence for the scale of grand
unification before the observation of proton decay.
