Measurement of ϕ(1020) Parameters in the $${{e}^{ + }}{{e}^{ - }} \to {{K}_{S}}{{K}_{L}}$$ Reaction
The $${{e}^{ + }}{{e}^{ - }} \to {{K}_{S}}{{K}_{L}}$$ cross section is measured in the center-of-mass energy range from 1000 to 1100 MeV in the experiment with the SND detector at the VEPP-2000 collider. The $$\phi (1020)$$ mass and width and the product of the branching fractions $$B(\phi \to {{K}_{S}}{{K}_{L}})B(\phi \to {{e}^{ + }}{{e}^{ - }})$$ are determined from the fit to the measured cross section in the vector meson dominance model.
