Using the initial-state radiation method, the e + e − → KSKL cross section from 1.98 to 2.54 GeV is measured in a data sample of 469 fb −1 collected with the BABAR detector. The results are used in conjunction with previous BABAR results for the e + e − → K + K − , e + e − → π + π − , e + e − → π + π − η , and e + e − → ω π π cross sections to investigate the nature of the resonance structure recently observed by the BESIII experiment in the e + e − → K+K− cross section.
