Isocurvature-Free QCD Axion Dark Matter from Inflaton-Driven Early QCD: the Necessity of Inflationary Plateaus

Barmak Shams Es Haghi, Evangelos I. Sfakianakis, Katherine Freese

Direct inflaton-gluon coupling suppresses axion isocurvature by dynamically raising the QCD confinement scale during inflation, selecting plateau-like models.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We (analytically) show that the mechanism selects plateau-like (p≥2) inflation: monomial models generically cause the confinement scale to grow too rapidly, while plateau models keep the QCD sector under perturbative control.

C2weakest assumption

A direct inflaton-gluon coupling exists and can dynamically raise the QCD confinement scale during inflation without violating perturbative control or requiring a specific potential beyond the ε(N) ∝ 1/N^p parametrization.

C3one line summary

Inflaton-gluon coupling raises the QCD scale early in inflation to eliminate axion isocurvature modes, selecting plateau inflation models for viable QCD axion dark matter.
