Abstract

With a 15M J/φ inclusive Monte Carlo sample, the absolute branching fraction of J/φ γη′ from the J/φ inclusive photon spectrum is measured to be Br(J/φ γ η′) (4.68 0.08 0.27) × 10^-3, which is in good agreement with the input value. The J/φ γf_J(2220) is also searched for using the same sample. Under our assumptions, the statistical significances of J/φ γf _J(2220) are larger than 7σ.
