Experimental Study of the Reaction $e^{+}{e}^{-}\to K_S{K}_L$ in the Energy Range $\sqrt{s}=1.04÷1.38$ GeV

Abstract

We present a measurement of the $e^{+}{e}^{-}\to K_S{K}_L$ cross section in the energy range $\sqrt{s}=1.04÷1.38$ GeV. For the energy $\sqrt{s}\ge 1.2$ GeV the cross section exceeds vector meson dominance model predictions with only $\rho (770)$, $\omega (783)$, and $\varphi (1020)$ mesons taken into account. Measured cross section agrees well with previous measurements.
