“…Similar to the case of ωð1960Þ, these two ω states were collected into the further states of PDG [1] because there was no further experimental confirmation. In 2018, the BESIII Collaboration reported a Xð2240Þ in the e þ e − → K þ K − process, which has the mass of 2239.2 AE 7.1 AE 11.3 MeV and the width of 139.8 AE 12.3 AE 20.6 MeV [14]. Xð2240Þ can be as the candidate of ωð4SÞ since it is possible that J PC , the quantum number, is suitable and the analysis of the Regge trajectory can support this scenario.…”

Since the present ω meson family has not been established, in this work we carry out an investigation of the mass spectrum and Okubo-Zweig-Iizuka allowed a two-body strong decay of the S-wave and the D-wave ω mesons, and make the comparison with the experimental data of these reported ω states and the ω-like Xð2240Þ state observed by BESIII. By this study, we not only suggest the possible assignments to these observed ω states under the framework of the ω meson family, but also predict three ω mesons [ωð5SÞ, ωð2DÞ, and ωð4DÞ which are still missing in experiment. The present study may provide valuable information to further construct the ω meson family. Considering the present running status of BESIII, we also suggest that BESIII should pay more attention to the issue of the ω meson by accumulating more data.

Using data samples with an integrated luminosity of 6.4 fb−1 collected by the BESIII detector operating at the BEPCII storage ring, the process of e+e− → γϕJ/ψ is studied. The processes of e+e− → ϕχc1,c2, χc1,c2 → γJ/ψ are observed with a significance of more than 10σ. The $$ \sqrt{s} $$ s -dependent cross section of e+e− → ϕχc1,c2 is measured between 4.600 and 4.951 GeV, and evidence of a resonance structure is found for the first time in the ϕχc2 process. We also search for the processes of e+e− → γX(4140), γX(4274) and γX(4500) via the γϕJ/ψ final state, but no obvious structures are found. The upper limits on the production cross section times the branching fraction for these processes at the 90% confidence level are reported.
