Radiative decays $J/\ddot{I}ˆ,\ddot{I}ˆ(2S)\to {\hat{I}}^3\hat{I}{\cdot }^{(\prime )}$ in perturbative QCD with relativistic corrections

Jun-Kang He, Chao-Jie Fan, Cong Wang

We present the first calculation of the radiative decays $J/\ddot{I}ˆ,\ddot{I}ˆ(2S)\to {\hat{I}}^3\hat{I}{\cdot }^{(\prime )}$ in perturbative QCD that includes the order-$q^2$ relativistic corrections in all…
