摘要 | With a 15M J/psi inclusive Monte Carlo sample, the absolute branching fraction of J/psi -> gamma eta' from the J/psi inclusive photon spectrum is measured to be Br(J/psi -> gamma eta')= (4.68 +/- 0.08 +/- 0.27) x 10(-3), which is in good agreement with the input value. The J/psi -> gamma fJ(2220) is also searched for using the same sample. Under our assumptions, the statistical significances of J/psi -> gamma fJ(2220) are larger than 7 sigma. |
