Light unflavored vector meson spectroscopy around the mass range of 2.4 ∼ 3 GeV and possible experimental evidence

In this work, we predict the spectroscopy behavior of these light unflavored vector mesons with masses at the range of 2.4 similar to 3 GeV, which are still missing in the experiment. By presenting their mass spectrum and studying their two-body Okubo-Zweig-lizuka allowed decay widths, we discuss the possible experimental evidences of these discussed states combining with the present experimental data. Especially, we strongly suggest that our experimental colleagues carry out the exploration of these higher states via the e(+) e(-) annihilation into light mesons. It is obvious that BESIII and Belle II will be potential experiments to achieve this target.

Automated summary

This paper predicts the spectroscopy behavior of light unflavored vector mesons with masses in the range of 2.4 to 3 GeV, which have not been observed in experiments. The possible experimental evidences of these states are discussed, and it is strongly suggested to explore these higher states through e(+) e(-) annihilation experiments. This work is of significance for the potential experiments BESIII and Belle II.
