| contents | The analyses of states with double $cs$ content and the search for exotics have recently gained much attention. The Belle experiment collected roughly 1 ab$^{-1}$ integrated luminosity data. While Belle II data-taking is in progress, we have performed a new search for exotic states and cross-section measurements with the full Belle data sets. Here we review the recent analysis of: (a) $e^+e^-\to D_s^{(*)+}+D_{sJ}^-$ + $c.c$. from both $Υ(2S)$ decays and continuum production at 10.52 GeV, using the Belle detector at KEKB; (b) the analysis of $e^+e^- \to η_c J/ψ$ + $c.c.$ and search for double charmonium states; (c) the study of $e^+e^- \to D_s^+D_{s0}(2317)^-$ + $c.c.$ and $e^+e^- \to D_s^+D_{s1}(2460)^-$ + $c.c.$ + anything else, in the continuum. Born cross-sections are evaluated, and a possible confirmation of the states seen in the invariant mass system of $J/ψϕ$ by LHCb in $B$ decays has been investigated. |
