Popis: This is the pre-print version of the Article. The official published version can be accessed from the links below. Copyright @ 2002 APS. We measure the branching fractions of the ψ(2S) meson to the leptonic final states e+e- and μ+μ- relative to that for ψ(2S)→J/ψπ+π-. The method uses ψ(2S) mesons produced in the decay of B mesons at the Υ(4S) resonance in a data sample collected with the BABAR detector at the Stanford Linear Accelerator Center. Using previous measurements for the ψ(2S)→J/ψπ+π- branching fraction, we determine the e+e- and μ+μ- branching fractions to be 0.0078±0.0009±0.0008 and 0.0067±0.0008±0.0007, respectively.
