abstract
The axion mass receives a large correction from small instantons if the QCD gets strongly coupled at high energies. We discuss the size of the new CP violating phases caused by the fact that the small instantons are sensitive to the UV physics. We also discuss the effects of the mass correction on the axion abundance of the Universe. Taking the small-instanton contributions into account, we propose a natural scenario of axion dark matter where the axion decay constant is as large as $10^{15\text{-}16}$GeV. The scenario works in the high-scale inflation models.

Why 4D? Spontaneous Dimensional Selection from Gauge Criticality
Gauge criticality of Yang–Mills, via racetrack confinement and 3D dynamical SUSY breaking, can stabilize radii so that a macroscopic 4D spacetime emerges without being put in by hand.

Feebly-Interacting Peccei-Quinn Model
A feebly-interacting PQ scalar with large wave-function renormalization can generate a large axion decay constant while keeping all mass scales near the TeV scale, predicting a light PQ Higgs and new dark matter scenarios.
