摘要：

We measure the branching fractions of the psi(2S) meson to the leptonic final states e(+) e(-) and mu(+) mu(-) relative to that for psi(2S)-->J/psipi(+) pi(-). The method uses psi(2S) mesons produced in the decay of B mesons at the Y(4S) resonance in a data sample collected with the BABAR detector at the Stanford Linear Accelerator Center. Using previous measurements for the psi(2S)-->J/psipi(+) pi(-) branching fraction, we determine the e(+)e(-) and mu(+) mu(-) branching fractions to be 0.0078+/-0.0009+/-0.0008 and 0.0067+/-0.0008+/-0.0007, respectively.
