Summary: | The processes e[superscript +]e[superscript -] →K[superscript 0][subscript S]K[superscript ±]π[superscript ∓]π[superscript 0] and e[superscript +]e[superscript -] →K[superscript 0][subscript S]K[supercript ±]π[superscript ∓]η are studied over a continuum of energies from threshold to 4 GeV with the initial-state photon radiation method. Using 454 fb[superscript -1] of data collected with the BABAR detector at the SLAC PEP-II storage ring, the first measurements of the cross sections for these processes are obtained. The intermediate resonance structures from K[superscript *0](Kπ)[superscript 0], K[superscript *](892)[superscript ±](Kπ)[superscript ∓], and K[superscript 0][subscript S]K[superscript ±]ρ[superscript ∓] are studied. The J/ψ is observed in all of these channels, and corresponding branching fractions are measured. |
