Abstract

We study the processes e^+e^− → K^0_SK^0_Lγ, K^0_SK^0_Lπ^+π^−γ, K^0_SK^0_Sπ^+π^−γ, and K^0_SK^0_SK^+K^−γ, where the photon is radiated from the initial state, providing cross section measurements for the hadronic states over a continuum of center-of-mass energies. The results are based on 469 fb^(−1) of data collected with the BABAR detector at SLAC. We observe the ϕ(1020) resonance in the K^0_SK^0_L final state and measure the product of its electronic width and branching fraction with about 3% uncertainty. We present a measurement of the e+e−→K0SK0L cross section in the energy range from 1.06 to 2.2 GeV and observe the production of a resonance at 1.67 GeV. We present the first measurements of the e^+e^− → K^0_SK^0_Lπ^+π^−, K^0_SK^0_Sπ^+π^−, and K^0_SK^0_SK^+K^− cross sections and study the intermediate resonance structures. We obtain the first observations of J/ψ decay to the K^0_SK^0_Lπ^+π^−, K^0_SK^0_Sπ^+π^−, and K^0_SK^0_SK^+K^− final states.
