“…It is important to note that the studies in Refs. [4,5,10] concluded that the contribution of the ρ (1700) to the process is small. Following the results, this paper will neglect the contribution of the amplitude with intermediate ρ (1700) meson.…”

The process of electron-positron annihilation into a pair of π 0 and ω mesons is considered in the framework of the SU(2)×SU(2) Nambu-Jona-Lasinio model. Contributions of intermediate photons, ρ(770) and ρ (1450) vector mesons are taken into account. It is shown that the bulk of the cross section at energies below 2 GeV is provided by the process with intermediate ρ (1450) state. The contribution due to single photon and ρ(770) exchange is in agreement with the vector meson dominance model. Numerical results are compared with experimental data.

“…Recently, in Ref. [10], the process was considered in frames of a nonrelativistic quark model. It is argued there that the process at energies below 2 GeV is dominated by the two-step process in which the primary quarkantiquark pair forms a ρ meson in the ground or excited state and then the vector meson decays into ω and π .…”

“…Theoretical works in the 3 P 0 quark model reveal that the reactions e + e − → ππ, πω,N N are dominated by the two-step process at low energies [9][10][11]. We expect the reaction e + e − →DD near threshold is mainly a two-step process, in line with our previous works and the vector meson dominance model which is successfully applied to study the reaction e + e − →DD in an effective Lagrangian approach [4].…”

We study the reaction e + e − →DD near threshold in the 3 P0 non-relativistic quark model, including as intermediate states the J/ψ, ψ(2S), ψ(3770) and ψ(4040) mesons. The work reveals that experimental data strongly favor one of the two ψ(2S) − ψ(3770) mixing angles derived by fitting to the e − e + partial decay widths of the ψ(2S) and ψ(3770) mesons. The meson X(3940) as well as the resonance around 3.9 GeV observed by Belle and BaBar Collaborations in the reaction e + e − →DD is unlikely to be a cc I G (J P C ) = 0 − (1 −− ) state.

“…As shown in PDG [8], ρð1450Þ can be assigned as the first radial excited state of ρð770Þ. By the analysis of the mass spectrum [9] and the study of total decay width [6] and the branching ratio of the ρð1700Þ → 2π; 4π [10] and e þ e − → ωπ 0 process [11], we may find that ρð1700Þ as a candidate of the ρð1 3 D 1 Þ meson state is suitable. It is the research status of some low-lying ρ-like states.…”

Very recently, the BABAR Collaboration indicated that there exists an explicit enhancement structure near 2.2 GeV when focusing on the e þ e − → π þ π − process again, which inspires our interest in studying the production of higher ρ mesonic states. Since the branching ratio of π þ π − channel of D-wave ρ states are much smaller than S-wave states, we choose ρð1900Þ and ρð2150Þ as the intermediate states in e þ e − → π þ π − , where ρð1900Þ and ρð2150Þ are treated as ρð3SÞ and ρð4SÞ states, respectively. Our result indicates that the BABAR's data of e þ e − → π þ π − around 2 GeV can be depicted well, which shows that this enhancement structure near 2.2 GeV existing in e þ e − → π þ π − can be due to the contribution from two ρ mesons, ρð1900Þ and ρð2150Þ. Additionally, this conclusion can be enforced by the consistence of the extracted values of Γ e þ e − Bðπ þ π − Þ of ρð1900Þ and ρð2150Þ in the whole fitting processes and the corresponding theoretical calculations. The present study of e þ e − → π þ π − data may provide valuable information to establish the ρ meson family.
