Status, open problems and prospects of the decay B^+ -> l^+ nu_l
arXiv:1012.1224
Abstract
The study of rare B-decays at SuperB provides unique opportunities to understand the Standard Model and constrain new physics. We discuss the new physics potential of the leptonic B^+ -> l^+ nu_l decays from the proposed SuperB experiment with 75ab-1 of data (5 nominal years of data taking).
