Structure at 2175 MeV in e+e−→ϕf0(980) observed via initial-state radiation
Bernard Aubert, M. Bóna, D. Boutigny, F. Couderc et autres
We study the initial-state-radiation processes ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}\ensuremath{\gamma}$ and ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}{\ensuremath{\pi}}^{0}\ensuremath{\gamma}$ using an integrated luminosity of $232\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected at the $\ensuremath{\Upsilon}(4S)$ mass with the BABAR detector at SLAC. Even though these reactions are dominated by intermediate states with excited kaons, we are able …
