Time-dependent Dalitz plot analysis of B0→D∓K0π± decays

B. Aubert, M. Bóna, Y. Karyotakis, J. P. Lees et autres

We present for the first time a measurement of the weak phase $2\ensuremath{\beta}+\ensuremath{\gamma}$ obtained from a time-dependent Dalitz plot analysis of ${B}^{0}\ensuremath{\rightarrow}{D}^{\ensuremath{\mp}}{K}^{0}{\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$ decays. Using a sample of approximately $347\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ pairs collected by the BABAR detector at the PEP-II asymmetric-energy storage rings …

Study of B¯→ΞcΛ¯c− and B¯→Λc+Λ¯c−K¯ decays atBABAR

B. Aubert, M. Bóna, D. Boutigny, Y. Karyotakis et autres

We report measurements of $B$-meson decays into two- and three-body final states containing two charmed baryons using a sample of $230\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $\ensuremath{\Upsilon}(4S)\ensuremath{\rightarrow}B\overline{B}$ decays. We find significant signals in two modes, measuring branching fractions $\mathcal{B}({B}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\Lambda}}_{c}^{+}{\overline{\ensuremath{\Lambda}}}_{c}^{\ensuremath{-}}{K}^{\ensuremath{-}})=(1.14\ifmmode\pm\else\textpm\fi{}0.15\ifmmode\pm\else\textpm\fi{}0.17\ifmmode\pm\else\textpm\fi{}0.60)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}3}$ and $\mathcal{B}({B}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\Xi}}_{c}^{0}{\overline{\ensuremath{\Lambda}}}_{c}^{\ensuremath{-}})\ifmmode\times\else\texttimes\fi{}\mathcal{B}({\ensuremath{\Xi}}_{c}^{0}\ensuremath{\rightarrow}{\ensuremath{\Xi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+})=(2.08\ifmmode\pm\else\textpm\fi{}0.65\ifmmode\pm\else\textpm\fi{}0.29\ifmmode\pm\else\textpm\fi{}0.54)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$, where the uncertainties are statistical, systematic, …

B. Aubert, M. Bóna, D. Boutigny, Y. Karyotakis et autres

We present measurements of the branching fractions for the decays ${B}^{\ifmmode\pm\else\textpm\fi{}}\ensuremath{\rightarrow}{a}_{1}^{\ifmmode\pm\else\textpm\fi{}}(1260){\ensuremath{\pi}}^{0}$ and ${B}^{\ifmmode\pm\else\textpm\fi{}}\ensuremath{\rightarrow}{a}_{1}^{0}(1260){\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$ from a data sample of $232\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ pairs produced in ${e}^{+}{e}^{\ensuremath{-}}$ annihilation through the $\ensuremath{\Upsilon}(4S)$ resonance. We measure the branching fraction $\mathcal{B}\mathbf{(}{B}^{\ifmmode\pm\else\textpm\fi{}}\ensuremath{\rightarrow}{a}_{1}^{\ifmmode\pm\else\textpm\fi{}}(1260){\ensuremath{\pi}}^{0}\mathbf{)}\ifmmode\times\else\texttimes\fi{}\mathcal{B}\mathbf{(}{a}_{1}^{\ifmmode\pm\else\textpm\fi{}}(1260)\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}\mathbf{)}=(13.2\ifmmode\pm\else\textpm\fi{}2.7\ifmmode\pm\else\textpm\fi{}2.1)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}6}$ with a significance of $4.2\ensuremath{\sigma}$, and the …

Measurement of CP -violating asymmetries in B0→(ρπ)0 using a time-dependent Dalitz plot analysis

B. Aubert, M. Bóna, D. Boutigny, Y. Karyotakis et autres

We report a measurement of $CP$-violating asymmetries in ${B}^{0}\ensuremath{\rightarrow}(\ensuremath{\rho}\ensuremath{\pi}{)}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}$ decays using a time-dependent Dalitz plot analysis. The results are obtained from a data sample of $375\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $\mathit{\ensuremath{\Upsilon}}(4S)\ensuremath{\rightarrow}B\overline{B}$ decays, collected by the BABAR detector at the PEP-II asymmetric-energy $B$ Factory at SLAC.

Measurements of CP -Violating Asymmetries in B0→a1±(1260)π∓ Decays

B. Aubert, M. Bóna, D. Boutigny, Y. Karyotakis et autres

We present measurements of $CP$-violating asymmetries in the decay ${B}^{0}\ensuremath{\rightarrow}{a}_{1}^{\ifmmode\pm\else\textpm\fi{}}(1260){\ensuremath{\pi}}^{\ensuremath{\mp}}$ with ${a}_{1}^{\ifmmode\pm\else\textpm\fi{}}(1260)\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{\mp}}{\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}{\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$. The data sample corresponds to $384\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ pairs collected with the BABAR detector at the PEP-II asymmetric $B$ factory at SLAC.

Determinations of |Vub| from Inclusive Semileptonic B Decays with Reduced Model Dependence

B. Aubert, R. Barate, D. Boutigny, F. Couderc et autres

We report two novel determinations of $|{V}_{ub}|$ with reduced model dependence, based on measurements of the mass distribution of the hadronic system in semileptonic $B$ decays. Events are selected by fully reconstructing the decay of one $B$ meson and identifying a charged …
