Leptonic B decays at BaBar

Abstract

We will present the most recent results on leptonic B decays $B^{\pm (0)}\to K^{\ast \pm (0)}\nu \bar{\nu }$ and $B^{\pm }\to {\mu }^{\pm }\nu$, based on the data collected by the BaBar detector at PEP-II, an asymmetric $e^{+}{e}^{-}$ collider at the center of mass energy of the ${\rm Y}(4S)$ resonance .
