© 2016 The Author(s)The e+e−→KS0KL0 cross section has been measured in the center-of-mass energy range 1004–1060 MeV at 25 energy points using 6.1×105 events with KS0→π+π− decay. The analysis is based on 5.9 pb−1 of an integrated luminosity collected with the CMD-3 detector at the VEPP-2000 e+e− collider. To obtain ϕ(1020) meson parameters the measured cross section is approximated according to the Vector Meson Dominance model as a sum of the ρ,ω,ϕ-like amplitudes and their excitations. This is the most precise measurement of the e+e−→KS0KL0 cross section with a 1.8% systematic uncertainty.
