Radiative charmonium decays in a contact-interaction model with dynamical quark anomalous magnetic moment
Yehan Xu, Zanbin Xing, Khépani Raya +1
The BESIII Collaboration has recently reported two measurements of the two-photon decay width of the meson. The 2024 result is significantly larger than most theoretical and…

Contact interaction treatment of for light-quark mesons
Yehan Xu, M. Atif Sultan, Khépani Raya +1
The and decays are evaluated within a Dyson-Schwinger and Bethe-Salpeter equations framework (here $\mathcal{V}=\{ρ^{\pm},K^{\star…
