Abstract
We study the processes e[superscript +]e[superscript −] → K[0 over S]K[0 over L]γ, K[0 over S]K[0 over L]π[superscript +]π[superscript −]γ, K[0 over S]K[0 over S]π[superscript +]π[superscript −]γ, and K[0 over S]K[0 over S]K[superscript +]K[superscript −]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[superscript −1] of data collected with the BABAR detector at SLAC. We observe the ϕ(1020) resonance in the K[0 over S]K[0 over 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[superscript +]e[superscript −] → K[0 over S]K[0 over L] 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[superscript +]e[superscript −] → K[0 over S]K[0 over L]π[superscript +]π[superscript −], K[0 over S]K[0 over S]π[superscript +]π[superscript −], and K[0 over S]K[0 over S]K[superscript +]K[superscript −] cross sections and study the intermediate resonance structures. We obtain the first observations of J/ψ decay to the K[0 over S]K[0 over L]π[superscript +]π[superscript −], K[0 over S]K[0 over S]π[superscript +]π[superscript −], and K[0 over S]K[0 over S]K[superscript +]K[superscript −] final states.
