Abstract

We present spectra of prompt electrons from decays of neutral and charged B mesons. The results are based on 140 fb^-1 of data collected by the Belle detector on the Υ(4S) resonance at the KEKB e⁺e ^- asymmetric collider. We tag Υ(4S)→BB̄ events by reconstructing a B meson in one of several hadronic decay modes; the semileptonic decay of the other B meson is inferred from the presence of an identified electron. We obtain for charged and neutral B mesons the partial rates of semileptonic decay, to electrons with momentum greater than 0.6 GeV/c in the B rest frame, and their ratio b₊/b₀=1.08±0. 05±0.02, where the first and second errors are statistical and systematic, respectively.

N2 - We present spectra of prompt electrons from decays of neutral and charged B mesons. The results are based on 140 fb-1 of data collected by the Belle detector on the Υ(4S) resonance at the KEKB e+e - asymmetric collider. We tag Υ(4S)→BB̄ events by reconstructing a B meson in one of several hadronic decay modes; the semileptonic decay of the other B meson is inferred from the presence of an identified electron. We obtain for charged and neutral B mesons the partial rates of semileptonic decay, to electrons with momentum greater than 0.6 GeV/c in the B rest frame, and their ratio b+/b0=1.08±0. 05±0.02, where the first and second errors are statistical and systematic, respectively.
