We present a search for the decays ${B}^{0}\ensuremath{\rightarrow}{e}^{+}{e}^{\ensuremath{-}}$, ${B}^{0}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$, and ${B}^{0}\ensuremath{\rightarrow}{e}^{\ifmmode\pm\else\textpm\fi{}}{\ensuremath{\mu}}^{\ensuremath{\mp}}$ using data collected with the BABAR detector at the PEP-II ${e}^{+}{e}^{\ensuremath{-}}$ collider at SLAC. Using a data set corresponding to $384\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ pairs, we do not find evidence of any of …

We present a measurement of the time-dependent $CP$-violating asymmetries in ${B}^{0}\ensuremath{\rightarrow}{K}_{S}^{0}{\ensuremath{\pi}}^{0}$ decays based on $383\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $\mathit{\ensuremath{\Upsilon}}(4S)\ensuremath{\rightarrow}B\overline{B}$ events collected by the BABAR experiment at the PEP-II asymmetric-energy $B$ Factory at the Stanford Linear Accelerator Center. We measure the direct $CP$-violating asymmetry ${C}_{{K}_{S}^{0}{\ensuremath{\pi}}^{0}}=0.24\ifmmode\pm\else\textpm\fi{}0.15\ifmmode\pm\else\textpm\fi{}0.03$ and …

We have searched for ${D}^{0}\ensuremath{-}{\overline{D}}^{0}$ mixing in ${D}^{*+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{D}^{0}$ decays with ${D}^{0}\ensuremath{\rightarrow}{K}^{(*)}e\ensuremath{\nu}$ in a sample of ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}c\overline{c}$ events produced near 10.58 GeV. The charge of the slow pion from charged ${D}^{*}$ decay tags the charm flavor at production, and it is required to …

We present measurements of the branching fractions for the Cabbibo suppressed decays ${D}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{0}$ and ${D}^{+}\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\pi}}^{0}$ based on a data sample corresponding to an integrated luminosity of $124.3\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$. The data were taken with the BABAR detector at the PEP-II $B$ Factory …
