Description
The branchig fraction of the rare B meson decay B->lnu are expected to be very small due to helicity suppression in the Standard Model. With the contributions from the new physics beyond the Standard Model, this may be avoided and the evidences of the process may be observed. With hadronic tagging method for a very clean experimental signature, this study is based on a set of data sample of 711fb-1 collected at the Y(4S) resonance energy, recorded by the Belle detector at the KEKB energy asymmetric e+e- collider.
