Study of the process e+e- → KS0 KS0 π+π- 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- → KS0 KS0 π+π- 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±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.
