Recent Results on Flavor Physics from BABAR

Abstract

We report an update to our previous measurement of the CKM element |Vub| using exclusive B → π`ν decays. In the charm sector we have performed a measurement of fDs using D + s → τ ντ decays, we have measured the mixing parameter yCP using the lifetime ratio 〈τKπ〉 〈τhh〉 in D decays, and we have also searched for CP violation using T-odd correlations in D decays to K+K−π+π−. Finally, in the tau sector we have performed a search for the lepton flavor violating decays τ± → e±γ and τ± → μ±γ.
