Revisiting the radiative decays J/ψ → γη(′) in perturbative QCD
In the framework of perturbative QCD, the radiative decays J/ψ→γη(′) are revisited in detail, where the involved one-loop integrals are evaluated analytically with the light quark masses kept. We have found that the sum of loop integrals is insensitive to the light quark masses and the branching rat...
