Abstract: | It is interesting to investigate the OZI-forbidden decays of orthoquarkoknium, J/ψ→γπ0(γη,γη'), J/ψ→ π+π- (π0 π0). At first glance, there is infrared divergence in the above processes. In this work, to clear the mist we use the factorization method with the light cone wavefunction of the final state light meson. We prove straightforwardly that the infrared divergence can be eliminated completely. |
