Abstract
Using the initial-state radiation method, the e[superscript +]e[superscript -]→K[subscript S]K[subscript L] cross section from 1.98 to 2.54 GeV is measured in a data sample of 469 fb[superscript -1] collected with the BABAR detector. The results are used in conjunction with previous BABAR results for the e[superscript +]e[superscript -]→K[superscript +]K[superscript -], e[superscript +]e[superscript -]→p[superscript +]p[superscript -], e[superscript +]e[superscript -]→p[superscript +]p[superscript -]?, and e[superscript +]e[superscript -]→ωππ cross sections to investigate the nature of the resonance structure recently observed by the BESIII experiment in the e[superscript +]e[superscript -]→K[superscript +]K[superscript -] cross section.
