“…The Born cross sections for the e + e − → ωπ + π − measured in this work are consistent with that for the e + e − → ωπ 0 π 0 obtained in ref. [52] within a factor of 2 given their uncertainties. Therefore, the pion production in the e + e − → ωππ process complies with the SU(3)-flavor symmetry.…”

In addition, the cross sections of the subprocesses via some intermediate states (e.g., e + e − → ωf 0 (500), ωf 0 (980), ωf 0 (1370), ωf 2 (1270), and b 1 (1235)π) are determined.…”

A partial wave analysis on the process e+e− → ωπ+π− is performed using 647 pb−1 of data sample collected by using the BESIII detector operating at the BEPCII storage ring at center-of-mass (c.m.) energies from 2.000 GeV to 3.080 GeV. The Born cross section of the e+e− → ωπ+π− process is measured, with precision improved by a factor of 3 compared to that of previous studies. A structure near 2.25 GeV is observed in the energy-dependent cross sections of e+e− → ωπ+π− and ωπ0π0 with a statistical significance of 7.6σ, and its determined mass and width are 2232 ± 19 ± 27 MeV/c2 and 93 ± 53 ± 20 MeV, respectively, where the first and second uncertainties are statistical and systematic, respectively. By analyzing the cross sections of subprocesses e+e− → ωf0(500), ωf0(980), ωf0(1370), ωf2(1270), and b1(1235)π, a structure, with mass M = 2200 ± 11 ± 17 MeV/c2 and width Γ = 74 ± 20 ± 24 MeV, is observed with a combined statistical significance of 7.9σ. The measured resonance parameters will help to reveal the nature of vector states around 2.25 GeV.

MeV as well as X(2222) which has mass of 2222 ± 7 ± 2 MeV and the width of 59 ± 30 ± 6 MeV. The mass spectrum of ω meson family is studied utilizing the modified Godfrey-Isgur model, and the two-body strong decays of X(2232), X(2200) and X(2222) within two different approaches of the 3 P 0 model. We find that the newly discovered states X(2232), X(2200) and X( 2222) may be the same and are most likely to be the ω(3D) state. The discovery could be useful in establishing entire ω mesons.
