Study Of The Process $E^+E^-\To K_s^0 K_s^0 Î ^+Î ^-$ In The C.M. Energy Range 1.6--2.0 Gev With The Cmd-3 Detector

Abstract

The cross section of the process $e^{+}{e}^{-}\to K_S^0{K}_S^0\ddot{I}{€}^{+}\ddot{I}{€}^{-}$ has been measured using a data sample of 56.7 pb${}^{-1}$ collected with the CMD-3 detector at the VEPP-2000 $e^{+}{e}^{-}$ collider. 596$\pm$27 and 210$\pm$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. A study of the production dynamics confirms the dominance of the $K^{\ast }(892{)}^{+}{K}^{\ast }(892{)}^{-}$ intermediate state.
