| dc.description | About 300 000 $e^+e^-\to ϕ\to K^0_L K^0_S$ events in the center of mass energy range from 984 to 1040 MeV were used for the measurement of the $ϕ$ meson parameters. The following results have been obtained: $σ_0 = (1367 \pm 15 \pm 21) nb, m_ϕ=(1019.504 \pm 0.011 \pm 0.033) MeV/c^2, Γ_ϕ=(4.477 \pm 0.036 \pm 0.022) MeV, Γ_{e^+e^-}\cdot B(ϕ\to K^0_L K^0_S) = (4.364 \pm 0.048 \pm 0.065)\cdot 10^{-4}$ MeV. | |
