About 300 000 e+e−→ϕ→KL0​KS0​ events in the center of mass
energy range from 984 to 1040 MeV were used for the measurement of the Ï•
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+e−​⋅B(ϕ→KL0​KS0​)=(4.364±0.048±0.065)⋅10−4 MeV.Comment: 13 pages, 5 figures, 5 table
