Resonances in $e^{+}{e}^{-}$ annihilation near 2.2 GeV

Abstract

Using the initial-state radiation method, the $e^{+}{e}^{-}\to K_S{K}_L$ 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 $e^{+}{e}^{-}\to K^{+}{K}^{-}$, $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}$, $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}\eta$, and $e^{+}{e}^{-}\to \omega \pi \pi$ cross sections to investigate the nature of the resonance structure recently observed by the BESIII experiment in the $e^{+}{e}^{-}\to K^{+}{K}^{-}$ cross section.
