Abstract :
It is interesting to investigate the OZI-forbidden radiative decays of orthoquarkonium, image, γη and image in perturbative QCD. In this work without the approximations adopted in literature we carry out a full one-loop calculation which involves integrations of 4- and 5-point loop functions. Our numerical results are in agreement with the present data. We also briefly discuss the decays of image, as well as image, image.
