Abstract

The e+e−→K0SK0L cross section has been measured in the center-of-mass energy range 1004–1060 MeV at 25 energy points using 6.1 ×105events with K0S→π+π−decay. The analysis is based on 5.9pb−1of 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−→K0SK0L cross section with a 1.8% systematic uncertainty
