Study of the process e+e-→KK in the center-of-mass energy range 1004-1060 MeV with the CMD-3 detector at e+e- VEPP-2000 collider

  • The e+e-→KS0+KL0 and e+e-→K-K+ cross sections have been measured in the center-of-mass energy range 1004-1060 MeV for 25 energy points with about 2%3% systematic uncertainties. The analysis is based on 5.5 pb-1 of integrated luminosity collected with the CMD-3 detector at the VEPP-2000 e+e- collider. The measured cross section is approximated according to vector meson dominance model as a sum of Ф, ω, ρ like amplitudes and their excitations, and Ф(1020) meson parameters have been obtained.
