Abstract
We study the processes e[superscript +]e[subscript -] →K[subcript S][superscript 0]K[subscript L][superscript 0]π[superscript 0]γ, K[subscript S][superscript 0]K[subscript L][superscript 0]ηγ, and K[subscript S][superscript 0]K[subscript L][superscript 0]π[superscript 0]π[superscript 0]γ, where the photon is radiated from the initial state, providing cross section measurements for the hadronic final states over a continuum of center-of-mass energies. The results are based on 469 fb[superscript -1] of data collected at or near the Υ(4S) resonance with the BABAR detector at SLAC. We present the first measurements of the e[superscript +]e[superscript -]→K[subscript S][superscript 0]K[subscript L][superscript 0]π[superscript 0], K[subscript S][superscript 0]K[subscript L][subscript 0]η, and K[subscript S][superscript 0]K[subscript L][superscript 0]π[superscript 0]π[superscript 0] cross sections up to a center-of-mass energy of 4 GeV and study their intermediate resonance structures. We observe J/ψ decays to all of these final states for the first time, present measurements of their J/ψ branching fractions, and search for ψ(2S) decays.
