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