摘要：
We present recent results on purely leptonic and electroweak penguin decays of the B meson based on data samples of up to 232 million B (B) over bar pairs collected by the BABAR experiment at the PEP-II B-Factory at SLAC. We present measurements of the branching fraction, the direct CP violating asymmetry, and photon energy spectrum of B -> Xs gamma decays using both a fully inclusive lepton-tagged technique as well as a sum of exclusive final states. Also included are results on the decay rates and asymmetries for the decays B -> K-(*) e(+)e(-). Finally, we present a search for the fully-leptonic decay B+ -> tau(+)v(tau).
