Strong decays of strange quarkonia

In this paper we evaluate strong decay amplitudes and partial widths of strange mesons (strangeonia and kaonia) in the ${}^3{P}_0$ decay model. We give numerical results for all energetically allowed open-flavor two-body decay modes of all $n\overline{s}$ and $s\overline{s}$ strange mesons in the $1S,$ $2S,$ $3S,$ $1P,$ $2P,$ $1D$ and $1F$ multiplets, comprising strong decays of a total of 43 resonances into 525 two-body modes, with 891 numerically evaluated amplitudes. This set of resonances includes all strange $q\overline{q}$ states with allowed strong decays expected in the quark model up to ca. 2.2 GeV. We use standard nonrelativistic simple harmonic oscillator quark model wave functions to evaluate these amplitudes, and quote numerical results for all amplitudes present in each decay mode. We also discuss the status of the associated experimental candidates, and note which states and decay modes would be especially interesting for future experimental study at hadronic, $e^{+}{e}^{-}$ and photoproduction facilities. These results should also be useful in distinguishing conventional quark model mesons from exotica such as glueballs and hybrids through their strong decays.
