Description
We report a new precise measurement of composition of electron partial width and branching fraction to hadrons G_ee*B(hadrons) for J/psi meson performed with the KEDR detector at the VEPP-4M e+e- collider. Lepton and total widths were calculated using table values of the J/psi lepton branching fractions .
Experimental methods and techniques applied during this analysis can be then directly used within data treatment from super-charm-tau factory. For instance, J/psi selection and fit tools developed can be used for fast resonance scanning and luminosity and beam spread determination.
