AB  - A stronger QCD in the early Universe renders the axion heavy, and thus can suppress the isocurvature perturbations of axion dark matter, relaxing the constraint on the inflation scale. Supersymmetry provides a natural framework for this because there is a flat direction involving Higgs fields. Stabilized at a large value during inflation, the Higgs flat direction leads to that the QCD interaction becomes strong at a high energy scale, making high scale inflation scenarios compatible with axion dark matter.
