The landscape of QCD axion models

Enrico Nardi, Luca Di Luzio, Luca Visinelli, Maurizio Giannotti

QCD axion models can extend the mass and coupling window beyond conventional limits while solving the strong CP problem.

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

Theoretical constructions that extend the window for the axion mass and couplings beyond conventional regions are highlighted and classified. Bounds from cosmology, astrophysics and experimental searches are reexamined and updated.

C2weakest assumption

The review assumes the cited literature provides a sufficiently complete and unbiased sample of models and bounds, without systematic omissions in the classification of extended windows.

C3one line summary

Review classifies QCD axion models extending the standard mass-coupling window and updates bounds from cosmology, astrophysics, and experiments.
