We present first evidence that the cosine of the CP-violating weak phase 2β is positive, and hence exclude trigonometric multifold solutions of the Cabibbo-Kobayashi-Maskawa (CKM) Unitarity Triangle using a time-dependent Dalitz plot analysis of B^{0}→D^{(*)}h^{0} with D→K_{S}^{0}π^{+}π^{-} decays, where h^{0}∈{π^{0},η,ω} denotes a …

We study the $\mathrm{\ensuremath{\Upsilon}}(1S)$ radiative decays to $\ensuremath{\gamma}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ and $\ensuremath{\gamma}{K}^{+}{K}^{\ensuremath{-}}$ using data recorded with the BABAR detector operating at the SLAC PEP-II asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider at center-of-mass energies at the $\mathrm{\ensuremath{\Upsilon}}(2S)$ and $\mathrm{\ensuremath{\Upsilon}}(3S)$ resonances. The $\mathrm{\ensuremath{\Upsilon}}(1S)$ resonance is reconstructed from the decay …

We use $(121\ifmmode\pm\else\textpm\fi{}1)$ million $\mathrm{\ensuremath{\Upsilon}}(3S)$ and $(98\ifmmode\pm\else\textpm\fi{}1)$ million $\mathrm{\ensuremath{\Upsilon}}(2S)$ mesons recorded by the BABAR detector at the PEP-II ${e}^{+}{e}^{\ensuremath{-}}$ collider at SLAC to perform a study of radiative transitions involving the ${\ensuremath{\chi}}_{b\mathrm{J}}(1P,2P)$ states in exclusive decays with ${\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}\ensuremath{\gamma}\ensuremath{\gamma}$ final states. We reconstruct …

We report a measurement of the ${D}^{0}$ meson mass using the decay chain ${D}^{*}(2010{)}^{+}\ensuremath{\rightarrow}{D}^{0}{\ensuremath{\pi}}^{+}$ with ${D}^{0}\ensuremath{\rightarrow}{K}^{\ensuremath{-}}{K}^{\ensuremath{-}}{K}^{+}{\ensuremath{\pi}}^{+}$. The data were recorded with the BABAR detector at center-of-mass energies at and near the $\mathit{\ensuremath{\Upsilon}}(4S)$ resonance, and correspond to an integrated luminosity of approximately $477\text{ …

We use $429\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of ${e}^{+}{e}^{\ensuremath{-}}$ collision data collected at the $\ensuremath{\Upsilon}(4S)$ resonance with the BABAR detector to measure the radiative transition rate of $b\ensuremath{\rightarrow}s\ensuremath{\gamma}$ with a sum of 38 exclusive final states. The inclusive branching fraction with a minimum photon …

We study inclusive dipion decays using a sample of $108\ifmmode\times\else\texttimes\fi{}{10}^{6}\ensuremath{\Upsilon}(3S)$ events recorded with the BABAR detector. We search for the decay mode $\ensuremath{\Upsilon}(3S)\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{h}_{b}(1P)$ and find no evidence for the bottomonium spin-singlet state ${h}_{b}(1P)$ in the invariant mass distribution recoiling against the ${\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ …

We use a sample of $384\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ events collected with the BABAR detector at the PEP-II ${e}^{+}{e}^{\ensuremath{-}}$ collider to study angular distributions in the rare decays $B\ensuremath{\rightarrow}{K}^{*}{\ensuremath{\ell}}^{+}{\ensuremath{\ell}}^{\ensuremath{-}}$, where ${\ensuremath{\ell}}^{+}{\ensuremath{\ell}}^{\ensuremath{-}}$ is either ${e}^{+}{e}^{\ensuremath{-}}$ or ${\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$. For low dilepton invariant masses, ${m}_{\ensuremath{\ell}\ensuremath{\ell}}<2.5\text{ }\text{ }\mathrm{GeV}/{c}^{2}$, …
