Light unflavor vector meson spectroscopy around the mass range of $2.4\sim 3$ GeV and possible experimental evidence

TL;DR

This paper predicts the properties of unobserved light unflavored vector mesons in the 2.4 to 3 GeV range, proposing experimental searches via $e^+e^-$ annihilation at BESIII and Belle II.

Contribution

The study provides theoretical predictions of the mass spectrum and decay widths of these mesons, guiding future experimental searches in this energy range.

Findings

Predicted mass spectrum of light unflavored vector mesons between 2.4 and 3 GeV.

Estimated two-body decay widths for these mesons.

Suggested experimental methods for detecting these states at BESIII and Belle II.

Abstract

In this work, we predict the spectroscopy behavior of these light unflavored vector mesons with masses at the range of $2.4\sim 3$ 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.
