The Ï•(1020) meson leptonic width has been determined from the combined
analysis of 4 major decay modes of the resonance (ϕ→K+K−,KL0​KS0​,π+π−π0,ηγ) studied with the CMD-2 detector at
the VEPP-2M e+e− collider. The following value has been obtained:
Γ(ϕ→e+e−)=1.235±0.006±0.022 keV.
The Ï•(1020) meson parameters in four main decay channels have been also
recalculated: B(ϕ→K+K−)=0.493±0.003±0.007, B(ϕ→KL​KS​)=0.336±0.002±0.006, B(ϕ→π+π−π0)=0.155±0.002±0.005, B(ϕ→ηγ)=0.0138±0.0002±0.0002.Comment: 14 pages, 3 figure
