Recent Results on Flavor Physics from BaBar

Abstract

We report an update to our previous measurement of the CKM element $|V_{ub}|$ using exclusive $B\to \pi \ell \nu$ decays. In the charm sector we have performed a measurement of $f_{Ds}$ using $D_s\to {\tau }^{+}{\nu }_{\tau }$ decays, we have measured the mixing parameter $y_{CP}$ using the lifetime ratio $\frac{⟨{\tau }_{K\pi }⟩}{⟨{\tau }_{hh}⟩}$ in $D^0$ decays, and we have also searched for CP violation using T-odd correlations in $D^0$ decays to $K^{+}{K}^{-}{\pi }^{+}{\pi }^{-}$. Finally, in the tau sector we have performed a search for the lepton flavor violating decays ${\tau }^{\pm }\to e^{\pm }\gamma$ and ${\tau }^{\pm }\to {\mu }^{\pm }\gamma$.
