Cross sections for the reactions $e^{+}{e}^{-}\to K_S^0{K}_L^0$, $K_S^0{K}_L^0{\pi }^{+}{\pi }^{-}$, $K_S^0{K}_S^0{\pi }^{+}{\pi }^{-}$, and $K_S^0{K}_S^0{K}^{+}{K}^{-}$ from events with initial-state radiation

The BABAR Collaboration, J. P. Lees

We study the processes $e^{+}{e}^{-}\to K_S^0{K}_L^0\gamma$, $K_S^0{K}_L^0{\pi }^{+}{\pi }^{-}\gamma$, $K_S^0{K}_S^0{\pi }^{+}{\pi }^{-}\gamma$, and $K_S^0{K}_S^0{K}^{+}{K}^{-}\gamma$, where the photon is radiated from the initial state, pro…
