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

3 Collaboration

摘要:

在VEPP-2000 $e^+e^-$对撞机上用CMD-3探测器采集了56.7 pb $^{-1}$的数据样本,测量了过程$e^+e^- \to K_S^0 K_S^0π^+π^-$的截面。在1.6- 2.0 GeV的质心能量范围内,分别选择了596个$\pm$ 27和210个$\pm$ 18信号事件,探测到6个和5个径迹。生产动力学的研究证实了$K^*(892)^+ K^*(892)^-$中间态的优势。

英文摘要:

The cross section of the process $e^+e^- \to K_S^0 K_S^0π^+π^-$ 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$\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.
