Resonances in e(+) e(-) annihilation near 2.2 GeV
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−→ωππ cross sectio...

| Sumario: | 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−→ωππ cross sections to investigate the nature of the resonance structure recently observed by the BESIII experiment in the e+e−→K+K− cross section. |
