Measurement of Γee(J/ψ) with KEDR detector

Abstract 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 ΓeeJ/ψ=5.550±0.056±0.089keV,ΓeeJ/ψ·ℬhadronsJ/ψ=4.884±0.048±0.078keV,ΓeeJ/...
