Contribution

First measurement of the $e^+e^- o K^+K^-$ cross section in this energy range at VEPP-2000, providing data consistent with prior BABAR results.

Findings

Results agree with previous BABAR measurements.

Measurement covers the energy range 1.05-2.0 GeV.

Data has comparable accuracy to previous studies.

Abstract

The $e^+e^-\to K^+K^-$ cross section is measured in the center-of-mass energy range $1.05-2.00$ GeV at the SND detector. The measurement is based on data with an integrated luminosity of 35 pb$^{-1}$ collected at the VEPP-2000 $e^+e^-$-collider. The obtained results are consistent with the previous most accurate data obtained in the BABAR experiment and have a comparable accuracy.
