• A bstract The product of the electronic width of the J/ψ meson and the branching fractions of its decay to hadrons and electrons has been measured using the KEDR detector at the VEPP-4M e + e − collider. The obtained values are Γ e e J / ψ = 5.550 ± 0.056 ± 0.089 keV , Γ e e J / ψ · ℬ hadrons J / ψ = 4.884 ± 0.048 ± 0.078 keV , Γ e e J / ψ · ℬ e e J / ψ = 0.3331 ± 0.0066 ± 0.0040 keV . The uncertainties shown are statistical and systematic, respectively. Using the result presented and the world-average value of the electronic branching fraction, one obtains the total width of the J/ψ meson: Γ = 92.94 ± 1.83 keV . These results are consistent with the previous experiments.
