Le résumé fourni par la source

The cross sections of the processes ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}}J/\ensuremath{\psi}$ and ${K}_{S}^{0}{K}_{S}^{0}J/\ensuremath{\psi}$ are measured via initial state radiation at center-of-mass energies between the threshold and 6.0 GeV using a data sample of $980\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected with the Belle detector on or near the $\mathrm{\ensuremath{\Upsilon}}(nS)$ resonances, where $n=1,2,\dots{},5$. The cross sections for ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}}J/\ensuremath{\psi}$ are at a few pb level and the average cross section for ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{K}_{S}^{0}{K}_{S}^{0}J/\ensuremath{\psi}$ is $1.8\ifmmode\pm\else\textpm\fi{}0.6(\text{stat})\ifmmode\pm\else\textpm\fi{}0.3(\text{syst})\text{ }\text{ }\mathrm{pb}$ between 4.4 and 5.2 GeV. All of them are consistent with previously published results with improved precision. A search for resonant structures and associated intermediate states in the cross section of the process ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}}J/\ensuremath{\psi}$ is performed.
