Abstract

We present physics opportunities and topics with the $s\bar{s}$ states (strangeonia) that can be studied with the BESIII detector operating at the BEPCII collider. Though the $\phi$ and $\eta/\eta^\prime$ states have long been established experimentally, only a handful of strangeonia are well known, in contrast to the rich $c\bar{c}$ charmoium system. An overview of the $s\bar{s}$ states and their experimental status is presented in this paper. The BESIII experiment has collected the world's largest samples of $J/\psi$, $\psi(2S)$, $\psi(3770)$, and direct $e^+e^-$ annihilations at energies below the $J/\psi$ and above 3.8\,GeV, and will continue to accumulate high quality, large integrated luminosity in the $\tau$-charm energy region. These data, combined with the excellent performance of the BESIII detector, will offer unprecedent opportunities to explore the $s\bar{s}$ system. In this paper we describe the experimental techniques to explore strangeonia with the BESIII detector.% at the BEPCII.
