“…In a word, there exist some hints of the higher excited ρ mesons according to the above experimental measurements, as pointed out in Ref. [21], and the existences of the higher excited ρ mesons above 2.4 GeV need to be confirmed by more precise experimental measurements in future. The theoretical predictions for their mass spectra and decay properties are crucial to search for them experimentally.…”

Although there are some experimental hints for the higher excited ρ mesons, our knowledge of their properties is much poor theoretically. Based on our recent work about excited ρ mesons [Phys.Rev.D104( 2021)034013], we present the mass spectra and decay properties of the higher excited ρ mesons with the modified Godfrey-Isgur quark model and the 3 P0 strong decay model, and compare our predictions with the experimental hints, which should be helpful to search for these higher excited ρ mesons.

“…Although more and more new hadronic states were observed in the past decades [27][28][29][30], light flavor meson family is far from being established. How to construct light flavor meson family with the reported experimental phenomena becomes an intriguing research topic [8,12,15,21,[31][32][33][34][35][36][37][38][39][40]. With data accumulation of e + e − collision at √ s ∼ 2 GeV, light flavor vector enhancement structures around 2.2 GeV were reported in e + e − → ωη [2] and e + e − → ωπ 0 π 0 [5], which can be related to higher ω mesonic states.…”

The e + e − → ωη and e + e − → ωπ 0 π 0 processes are ideal platforms to search for higher ω states. Focusing on the observations of two enhancement structures around 2.2 GeV existing in e + e − → ωη and e + e − → ωπ 0 π 0 at BESIII, we analyze how the ω(4S ) and ω(3D) states play the role in the e + e − → ωη and e + e − → ωπ 0 π 0 processes. The present study is supported by theoretical ω mesonic spectroscopy. For reproducing the data of the cross sections of e + e − → ωη and ωπ 0 π 0 , the intermediate ω(4S ) and ω(3D) should be introduced, which indicates that the enhancement structures around 2.2 GeV existing in e + e − → ωη and ωπ 0 π 0 contain the ω(4S ) and ω(3D) signals. Nonetheless, in the process e + e − → ωη, the ω(4S ) plays a dominant role, while the ω(4S ) and ω(3D) have similar sizable contributions in the process of e + e − → ωπ 0 π 0 , which leads to a difference in the line shape of enhancement structure in the cross sections under the interference effect. Thus, we find a solution to alleviate the puzzling difference of resonance parameter of two reported enhancement structures around 2.2 GeV existing in e + e − → ωη and e + e − → ωπ 0 π 0 at BESIII. The present study provides valuable information to construct ω meson family, which can be accessible at future experiment like BESIII.
