We study a class of gauge groups that can automatically yield a perturbatively exact Peccei-Quinn symmetry, and we outline a model in which the axion quality problem is solved at all operator dimensions. Gauge groups belonging to this class can also enforce and protect accidental symmetries of the clockwork type, and we present a toy model where an `invisible' axion arises from a single breaking of the gauge and global symmetries.

  1. A quality-coupling relation in chiral $U(1)_{B-L}$ axion model

    hep-ph 2026-08 conditional novelty 6.0 of 10

    In this chiral U(1)_{B-L} axion model, demanding high axion quality forces a minimal axion-electron coupling that can exceed standard KSVZ-model predictions.

  2. The Minimal High-Quality QCD Axion

    hep-ph 2026-07 conditional novelty 5.5 of 10

    A flat-interval 5D U(1) Wilson-line axion with 4D KSVZ/DFSZ anomaly sector supplies exponential quality protection while remaining minimal.
