The process e+e- → K0 LK0 S has been studied with the CMD-2 detector using about 950 events detected in the center-of-mass energy range from 1.05 to 1.38 GeV. The cross section exceeds the expectation based on the contributions of the ρ(770), ω(782) and φ(1020) mesons only. © 2002 Elsevier Science B.V. All rights reserved.
