摘要：

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(-) -> pi(+)pi(-), e(+) e(-) -> pi(+)pi(-)eta, and e(+)e (-)-> omega pi pi cross sections to investigate the nature of the resonance structure recently observed by the BESIII experiment in the e(+) e(-)-> K+K- cross section.
