Understand

We propose a novel mechanism to suppress the isocurvature perturbations of the QCD axion.

The point is that the QCD interactions become strong at an intermediate or high energy scale in the very early Universe, if the Higgs field has a sufficiently large expectation value.
The effective QCD scale can be even higher in the presence of extra colored particles.
We show that the QCD axion then becomes so heavy during inflation that its isocurvature perturbations are significantly suppressed, thereby relaxing the constraint on the inflation scale.
