abstract
Using a data sample of $448\times10^{6}$ $\psi(3686)$ events collected with the BESIII detector operating at the BEPCII storage ring, the decays $\psi(3686)\rightarrow\gamma\eta$ and $\psi(3686)\rightarrow\gamma\pi^{0}$ are observed with a statistical significance of $7.3\sigma$ and $ 6.7\sigma$, respectively. The branching fractions are measured to be $\mathcal{B}(\psi(3686)\rightarrow\gamma\eta)=(0.85\pm0.18\pm0.05)\times10^{-6}$ and $\mathcal{B}(\psi(3686)\rightarrow\gamma\pi^{0})=(0.95\pm0.16\pm0.05)\times10^{-6}$. In addition, we measure the branching fraction of $\psi(3686)\rightarrow\gamma\eta'$ to be $\mathcal{B}(\psi(3686)\rightarrow\gamma\eta')=(125.1\pm2.2\pm6.2)\times 10^{-6}$, with improved precision compared to previous results.

$\eta$ and $\eta'$ meson production in $J/\psi$ radiative decays from lattice QCD
hep-lat 2025-06 accept novelty 8.0 of 10
A 2+1 flavor lattice QCD calculation determines the J/psi to gamma eta and J/psi to gamma eta' transition form factors separately for the first time, finding rates below experiment.

Radiative decays $J/\psi,\,\psi(2S)\rightarrow\gamma\eta^{(\prime)}$ in perturbative QCD with relativistic corrections
hep-ph 2026-07 conditional novelty 6.0 of 10
Order-q² relativistic corrections in pQCD roughly double J/ψ→γη(') rates and favor a smaller mixing angle, while ψ(2S) rates overshoot data and may require coherent ηc mixing.
