The branching fractions of the decays B+ → ηl+νl and B+ → ηl+νl are measured, where l is either an electron or a muon, using a data sample of 711 fb−1 containing 772 × 106 BB̅ pairs collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider. To reduce the dependence of the result on the form factor model, the measurement is performed over the entire q2 range. The resulting branching fractions are B(B+ → η ℓ + ν ℓ)=(2.83 …

The branching fractions of the decays B+ → ηl+νl and B+ → η0 lþνl are measured, where l is either an electron or a muon, using a data sample of 711 fb−1 containing 772 × 106 BB̅ pairs collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider. To reduce the dependence of the result on the form factor model, the measurement is performed over the entire q2 range. The resulting branching fractions are B(B+ → ηlþνl)=(2.83 ± 0.55(stat.) ± 0.34(syst.) )× 10 …

We report on a precision measurement of the ratio Rϒð3SÞ τμ ¼ Bðϒð3SÞ → τþτ−Þ=Bðϒð3SÞ → μþμ−Þ using data collected with the BABAR detector at the SLAC PEP-II eþe− collider. The measurement is based on a 28 fb−1 data sample collected at a center-of-mass energy of 10.355 GeV corresponding to a sample of 122 million ϒð3SÞ mesons. The ratio is measured to be Rϒð3SÞ τμ ¼ 0.966 0.008stat 0.014syst and is in agreement with the standard model prediction of 0.9948 within 2 standard deviations. The uncertainty in Rϒð3SÞ τμ is almost an order of magnitude smaller than the only previous …

We report the observation of the rare charm decay D0 → K−πþeþe−, based on 468 fb−1 of eþe− annihilation data collected at or close to the center-of-mass energy of the ϒð4SÞ resonance with the BABAR detector at the SLAC National Accelerator Laboratory. We find the branching fraction in the invariant mass range 0.675 < m(e+e−) < 0.875 GeV=c2 of the electron-positron pair to be B(D0 → K−π+e+e−) = (4.0 ± 0.5 ± 0.2 ± 0.1) × 10−6, where the first uncertainty is statistical, the second …
