Strange Quarkonium States at BESIII

We present physics opportunities and topics with the ss̅ states (strangeonia) that can be studied with the BESIII detector operating at the BEPC II collider. Though the φ and ηηʹ states have long been established experimentally, only a handful of strangeonia are well known, in contrast to the rich cc̅ charmoium system. An overview of the ss̅ states and their experimental status is presented in this paper. The BESIII experiment has collected the world's largest sarnples of J/ψ, ψ(2Sʹ), 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 unprecedented opportunities to explore the ss̅ r system. In this paper we describe the experimental techniques to explore strangeonia with the BESIII detector.
