abstract

We pursue the calculation of the model-independent component of the axion-photon-photon coupling in the $U(3)$ chiral perturbation theory up to next-to-leading order, with the emphasis on the isospin breaking effect. The mixing of the $\pi^0$-$\eta$-$\eta'$-axion system is revised as well by working out the complete linear isospin-breaking terms. Our calculation shows that the isospin-breaking correction to the axion-photon-photon coupling amounts to more than 15%, comparing with the result in the isospin limit.

  1. Catalogues of Cosmologically Self-Consistent Hadronic QCD Axion Models

    hep-ph 2024-12 conditional novelty 7.0 of 10

    Hadronic axion models with d=6 and d=7 heavy-quark decay operators can produce two new cosmologically viable 'islands' at f_a ~ 10^12 and 10^14 GeV, extending the post-inflationary axion search window.

  2. The structure of multi-axion solutions to the strong CP problem

    hep-ph 2026-05 unverdicted novelty 6.0 of 10

    Multi-axion theories solving the strong CP problem produce varied mass-coupling relations via a general sum rule that depends on the details of PQ symmetry breaking and anomaly alignments.

  3. Unified study of two-meson and axion-meson production from semileptonic tau decays within resonance chiral framework

    hep-ph 2025-07 conditional novelty 6.0 of 10

    Within a resonance chiral model, hadron resonances boost predicted tau decays into pion/K plus axion by factors of 7.5 and 19.2, with branching ratios and forward-backward asymmetries also predicted.
