Measurement of the D*(2010)+−D+ Mass Difference

J.-P. Lees, V. Poireau, V. Tisserand, E. Graugés et autres

We measure the mass difference, $\mathrm{\ensuremath{\Delta}}{m}_{+}$, between the ${D}^{*}(2010{)}^{+}$ and the ${D}^{+}$ using the decay chain ${D}^{*}(2010{)}^{+}\ensuremath{\rightarrow}{D}^{+}{\ensuremath{\pi}}^{0}$ with ${D}^{+}\ensuremath{\rightarrow}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{+}$. The data were recorded with the BABAR detector at center-of-mass energies at and near the $\mathrm{\ensuremath{\Upsilon}}(4S)$ resonance, and correspond to an integrated luminosity …

Study of B±,0→J/ψK+K−K±,0 and search for B0→J/ψϕ atBaBar

J. P. Lees, V. Poireau, V. Tisserand, E. Graugés et autres

We study the rare $B$ meson decays ${B}^{\ifmmode\pm\else\textpm\fi{},0}\ensuremath{\rightarrow}J/\ensuremath{\psi}{K}^{+}{K}^{\ensuremath{-}}{K}^{\ifmmode\pm\else\textpm\fi{},0}$, ${B}^{\ifmmode\pm\else\textpm\fi{},0}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\phi}{K}^{\ifmmode\pm\else\textpm\fi{},0}$, and search for ${B}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\phi}$, using $469\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ events collected at the $\mathrm{\ensuremath{\Upsilon}}(4S)$ resonance with the BABAR detector at the PEP-II ${e}^{+}{e}^{\ensuremath{-}}$ asymmetric energy collider. We present new measurements of branching fractions and a …

Study of B¯→Xuℓν¯ decays in BB¯ events tagged by a fully reconstructed B -meson decay and determination of |Vub|

J. P. Lees, V. Poireau, V. Tisserand, J. Garra Ticó et autres

We report measurements of partial branching fractions for inclusive charmless semileptonic $B$ decays $\overline{B}\ensuremath{\rightarrow}{X}_{u}\ensuremath{\ell}\overline{\ensuremath{\nu}}$ and the determination of the Cabibbo--Kobayashi--Maskawa (CKM) matrix element $|{V}_{ub}|$. The analysis is based on a sample of $467\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $\ensuremath{\Upsilon}(4S)\ensuremath{\rightarrow}B\overline{B}$ decays recorded with the BABAR detector at the …

Cross sections for the reactions e+e−→K+K−π+π− , K+K−π0π0 , and K+K−K+K− measured using initial-state radiation events

J. P. Lees, V. Poireau, E. Prencipe, V. Tisserand et autres

We study the processes ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}\ensuremath{\gamma}$, ${K}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}{\ensuremath{\pi}}^{0}\ensuremath{\gamma}$, and ${K}^{+}{K}^{\ensuremath{-}}{K}^{+}{K}^{\ensuremath{-}}\ensuremath{\gamma}$, where the photon is radiated from the initial state. About 84 000, 8000, and 4200 fully reconstructed events, respectively, are selected from $454\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of BABAR data. The invariant mass of the hadronic …

Search for the decay modes B±→h±τℓ

J. P. Lees, V. Poireau, V. Tisserand, J. Garra Ticó et autres

We present a search for the lepton flavor violating decay modes ${B}^{\ifmmode\pm\else\textpm\fi{}}\ensuremath{\rightarrow}{h}^{\ifmmode\pm\else\textpm\fi{}}\ensuremath{\tau}\ensuremath{\ell}$ ($h=K$, $\ensuremath{\pi}$; $\ensuremath{\ell}=e$, $\ensuremath{\mu}$) using the BABAR data sample, which corresponds to $472\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ pairs. The search uses events where one $B$ meson is fully reconstructed in one of several …
