Abstract

About 300 000 e+eϕKL0KS0e^+e^-\to \phi\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\phi meson parameters. The following results have been obtained: σ0=(1367±15±21)nb,mϕ=(1019.504±0.011±0.033)MeV/c2,Γϕ=(4.477±0.036±0.022)MeV,Γe+eB(ϕKL0KS0)=(4.364±0.048±0.065)104\sigma_0 = (1367 \pm 15 \pm 21) nb, m_{\phi}=(1019.504 \pm 0.011 \pm 0.033) MeV/c^2, \Gamma_\phi=(4.477 \pm 0.036 \pm 0.022) MeV, \Gamma_{e^+e^-}\cdot B(\phi\to K^0_L K^0_S) = (4.364 \pm 0.048 \pm 0.065)\cdot 10^{-4} MeV.
