| アブストラクト: |
We have computed the possible background to the pure leptonic decay, B/D-> l nu, caused by the radiative B/D-> l nu gamma (when gamma is very soft). Our analysis shows that even for the most serious case which is B-> mu nu, we can suppress this background by improving the lepton energy sensitivity. |
