Abstract

The e+e- → 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.
