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

TL;DR

This study measures the cross section of the process $e^+e^- o K_S^0 K_S^0 o ext{final states}$ in the 1.6--2.0 GeV energy range, revealing the dominance of the $K^*(892)$ intermediate state using the CMD-3 detector.

Contribution

First measurement of the cross section for $e^+e^- o K_S^0 K_S^0 o ext{final states}$ in the specified energy range with detailed production dynamics analysis.

Findings

Cross section measured with 56.7 pb$^{-1}$ data sample.

Dominance of the $K^*(892)^+ K^*(892)^-$ intermediate state.

Identification of signal events with six and five tracks.

Abstract

The cross section of the process $e^+e^- \to K_S^0 K_S^0\pi^+\pi^-$ 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 $K^*(892)^+ K^*(892)^-$ intermediate state.
