Abstract

The cross section of the process e+e−→K0SK0Sπ+π−has been measured using a data sample of 56.7 pb−1collected with the CMD-3 detector at the VEPP-2000 e+e−collider. 596±27 and 210±18 signal events have been selected with six and five detected tracks, respectively, in the center-of-mass energy range 1.6–2.0 GeV. The total systematic uncertainty of the cross section is about 10%. The study of the production dynamics confirms the dominance of the K∗(892)+K∗(892)−intermediate state.
