Measurement of the branching ratio of relative to decays with a semileptonic tagging method
Abstract
Here, we report a measurement of the ratio , where denotes an electron or a muon. The results are based on a data sample containing pairs recorded at the resonance with the Belle detector at the KEKB collider. We select a sample of pairs by reconstructing both mesons in semileptonic decays to . We measure , which is within of the Standard Model theoretical expectation, where the standard deviation includes systematic uncertainties. We use this measurement to constrain several scenarios of new physics in a model-independent technique.

The results are based on a data sample containing 772×106BB¯ pairs recorded at the Υ(4S) resonance with the Belle detector at the KEKB e+e- collider. We select a sample of B0B¯0 pairs by reconstructing both B mesons in semileptonic decays to D*∓ℓ±. We measure R(D*)=0.302±0.030(stat)±0.011(syst), which is within 1.6σ of the Standard Model theoretical expectation, where the standard deviation σ includes systematic uncertainties. We use this measurement to constrain several scenarios of new physics in a model-independent technique.},
