Results are presented of searches for the production of supersymmetric particles decaying into final states with missing transverse momentum and exactly two isolated leptons in √ s = 7 TeV proton-proton collisions at the Large Hadron Collider.Search strategies requiring lepton pairs with …

We report results of a search for $CPT$ and Lorentz violation in ${B}^{0}\mathrm{\text{\ensuremath{-}}}{\overline{B}}^{0}$ oscillations using inclusive dilepton events from $232\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $\ensuremath{\Upsilon}(4S)\ensuremath{\rightarrow}B\overline{B}$ decays recorded by the BABAR detector at the PEP-II $B$ Factory at SLAC. We find $2.8\ensuremath{\sigma}$ significance, compatible with no signal, …

We present a search for the lepton flavor violating decay ${B}^{+}\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\tau}}^{\ensuremath{\mp}}{\ensuremath{\mu}}^{\ifmmode\pm\else\textpm\fi{}}$ using $383\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ events collected by the BABAR experiment. The branching fraction for this decay can be substantially enhanced in new physics models. The kinematics of the tau from the signal …

We present the first observation of the decay ${B}^{+}\ensuremath{\rightarrow}{\ensuremath{\rho}}^{+}{K}^{0}$, using a data sample of $348\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected at the $\ensuremath{\Upsilon}(4S)$ resonance with the BABAR detector. The branching fraction and charge asymmetry are measured to be $({8.0}_{\ensuremath{-}1.3}^{+1.4}\ifmmode\pm\else\textpm\fi{}0.6)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}6}$ and $(\ensuremath{-}12.2\ifmmode\pm\else\textpm\fi{}16.6\ifmmode\pm\else\textpm\fi{}2.0)%$, respectively, where the …
