Abstract:

We present a measurement of the

e^+e^-\to K_SK_L

cross section in the energy range

\sqrt{s}=1.04 \div 1.38

GeV. For the energy

\sqrt{s}\geq 1.2

GeV the cross section exceeds vector meson dominance model predictions with only

\rho(770)

,

\omega(783)

, and

\phi(1020)

mesons taken into account. Measured cross section agrees well with previous measurements.
