Description
In this work the study of the $e^+e^- → K^+K^-\pi^+\pi^-$ process in the center-of-mass energy range from 1.4 to 2 GeV is presented. The data collected with the CMD-3 detector at the VEPP-2000 collider at 82 center-of-mass energy points have been used. Their integrated luminosity has amounted to about 500 $pb^{-1}$. The $e^+e^- → K^+K^-\pi^+\pi^-$ cross section has been measured, and the results are compatible with the BaBar and the previous CMD-3 results. The intermediate states $K^*(892)^{0}K\pi$, $K^*(892)^{0}\bar{K}^*(892)^{0}$, $\rho(770)KK$, $\phi(1020)\rho(770)$, $\phi(1020)f_0(500)$ have been seen. This study results are preliminary.
