“…The second one is that e þ e − → π þ π − occurs via intermediate ρ states. When trying to reproduce the line shape of the cross section of e þ e − → π þ π − process around 2 GeV reported by the BABAR Collaboration recently [4], we need to choose suitable intermediate ρ meson states. The collected information in Table I shows that ρð1900Þ, ρð2000Þ, ρð2150Þ, and ρð2270Þ should be considered in our calculation.…”

“…By adopting initial state radiation method which plays crucial role to the observation of charmoniumlike state Yð4260Þ from the e þ e − → J=ψπ þ π − process [2], the BABAR Collaboration measured the e þ e − → π þ π − process [3] by the collected 232 fb −1 experimental data, by which the cross section information of e þ e − → π þ π − from the π þ π − threshold to center-ofmass energy of 3 GeV was obtained. Very recently, the BABAR Collaboration focused on e þ e − → π þ π − again, and indicated that there exists an explicit enhancement structure near 2.2 GeV in the π þ π − invariant mass spectrum [4]. This phenomenon stimulates our interest in studying e þ e − → π þ π − since it has a close relation to establish light vector mesons around 2 GeV, which is one part of whole study of light hadron spectroscopy.…”

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.

In this work we calculate the mass spectrum of strangeonium up to the multiplet within a nonrelativistic linear potential quark model. Furthermore, using the obtained wave functions, we also evaluate the strong decays of the strangeonium states with the model. Based on our successful explanations of the well established states , , , , and , we further discuss the possible assignments of strangeonium-like states from experiments by combining our theoretical results with observations. It is found that some resonances, such as and , listed by the Particle Data Group, and and , newly observed by BESIII, may be interpreted as strangeonium states. The possibility of as a candidate for or cannot be excluded. We expect our results to provide useful references for looking for the missing states in future experiments.

Fully-light vector tetraquark states with explicit P-wave via QCD sum rules*

In this paper, we apply the QCD sum rules to study the vector fully-light tetraquark states with anexplicit P-wave between the diquark and antidiquark pair. We observed that the $C\gamma_\alpha\otimes\stackrel{\leftrightarrow}{\partial}_\mu\otimes\gamma^\alpha C$ (or $C\gamma_\alpha\otimes\stackrel{\leftrightarrow}D_\mu\otimes\gamma^\alpha C$) type current with fully-strange quarks couples potentially to a tetraquark state with the mass $2.16 \pm 0.14 \,\rm{GeV}$, which supports assigning the $Y/\phi(2175)$ as the diquark-antidiquark type tetraquark state with the $J^{PC}=1^{--}$. The $qs\bar{q}\bar{s}$ and $ss\bar{s}\bar{s}$ vector tetraquark states with the structure $C\gamma_\mu\otimes \stackrel{\leftrightarrow}{\partial}_\alpha \otimes\gamma^\alpha C + C\gamma^\alpha \otimes\stackrel{\leftrightarrow}{\partial}_\alpha \otimes\gamma_\mu$ (or $C\gamma_\mu\otimes \stackrel{\leftrightarrow}D_\alpha \otimes\gamma^\alpha C + C\gamma^\alpha \otimes\stackrel{\leftrightarrow}D_\alpha \otimes\gamma_\mu$) are consistent with the $X(2200)$ and $X(2400)$ respectively, which lie in the region $2.20$ to $2.40\,\rm{GeV}$. The central values of the masses of the fully-strange vector tetraquark states with an explicit P-wave are about $2.16-3.13\,\rm{GeV}$ (or $2.16-3.16\,\rm{GeV}$), and the predictions for other fully-light vector tetraquark states with and without hidden-strange are also presented.
