Abstract

Based on a sample of (1310.6±10.5)×106 J/ψ events collected with the BESIII detector operating at the BEPCII storage ring, a partial wave analysis of the decay J/ψ→γφφ is performed in order to study the intermediate states. Results of the partial wave analysis show that the structures are predominantly 0-+ states. The existence of the η(2225) is confirmed, and its resonance parameters are measured. Two additional pseudoscalar states, the η(2100) with a mass of 2050-24-26+30+75 MeV/c2 and a width of 250-30-164+36+181 MeV/c2 and the X(2500) with a mass of 2470-19-23+15+101 MeV/c2 and a width of 230-35-33+64+56 MeV/c2, are observed. In addition to these three pseudoscalar states, the scalar state f0(2100), and three tensor states, the f2(2010), f2(2300) and f2(2340), are observed in the process J/ψ→γφφ. The product branching fractions B(J/ψ→γX)×B(X→φφ) are reported.
