Radiative decays of $J / ψ, ψ (2 S) \to γ η^{(')}$ in perturbative QCD with relativistic corrections

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

We present the first calculation of the radiative decays $J / ψ, ψ (2 S) \to γ η^{(')}$ in perturbative QCD that includes the order- $q^{2}$ relativistic corrections in all thr…

Heavy quarkonium decay $V \to g g g$ with both relativistic and QCD radiative corrections

Hong-Mei Jiang, Chao-Jie Fan, Jun-Kang He +1

In the heavy quarkonium decay process $V \to g g g$ ( $V = J / ψ, Υ$ ), making a definite prediction including relativistic corrections has so far remained a significant challenge. In t…

Revisiting the $P$ -wave charmonium radiative decays $h_{c} \to γ η^{(')}$ with relativistic corrections

Jun-Kang He, Chao-Jie Fan

The $P$ -wave charmonium decays $h_{c} \to γ η^{(')}$ are revisited by taking into account relativistic corrections. The decay amplitudes are derived in the Bethe-Salpeter…

Radiative decays of $h_{c}$ to the light mesons $η^{(')}$ : A perturbative QCD calculation

Chao-Jie Fan, Jun-Kang He

We study the radiative decays $h_{c} \to γ η^{(')}$ in the framework of perturbative QCD and evaluate analytically the one-loop integrals with the light quark masses kept…
