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

Abstract

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