Measurement of CP observables in B±→DCPK± decays and constraints on the CKM angle γ

P. del Amo Sanchez, J. P. Lees, V. Poireau, Elisabetta Prencipe et autres

Using the entire sample of $467\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $\ensuremath{\Upsilon}(4S)\ensuremath{\rightarrow}B\overline{B}$ decays collected with the BABAR detector at the PEP-II asymmetric-energy $B$ factory at the SLAC National Accelerator Laboratory, we perform an analysis of ${B}^{\ifmmode\pm\else\textpm\fi{}}\ensuremath{\rightarrow}D{K}^{\ifmmode\pm\else\textpm\fi{}}$ decays, using decay modes in which the neutral $D$ meson decays …

Constraints on the CKM angle γ in B0→D¯0K*0 and B0→D0K*0 from a Dalitz analysis of D0 and D¯0 decays to KSπ+π−

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

We present constraints on the angle $\ensuremath{\gamma}$ of the unitarity triangle with a Dalitz analysis of neutral $D$ decays to ${K}_{S}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ from the processes ${B}^{0}\ensuremath{\rightarrow}{\overline{D}}^{0}{K}^{*0}$ (${\overline{B}}^{0}\ensuremath{\rightarrow}{D}^{0}{\overline{K}}^{*0}$) and ${B}^{0}\ensuremath{\rightarrow}{D}^{0}{K}^{*0}$ (${\overline{B}}^{0}\ensuremath{\rightarrow}{\overline{D}}^{0}{\overline{K}}^{*0}$) with ${K}^{*0}\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ (${\overline{K}}^{*0}\ensuremath{\rightarrow}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$). Using a sample of $371\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ pairs collected with the …

Measurement of time dependent CP asymmetry parameters in B0 meson decays to ωKS0 , η′K0 , and π0KS0

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

We present measurements of the time-dependent $CP$-violation parameters $S$ and $C$ in the decays ${B}^{0}\ensuremath{\rightarrow}\ensuremath{\omega}{K}_{S}^{0}$, ${B}^{0}\ensuremath{\rightarrow}{\ensuremath{\eta}}^{\ensuremath{'}}{K}^{0}$, reconstructed as ${\ensuremath{\eta}}^{\ensuremath{'}}{K}_{S}^{0}$ and ${\ensuremath{\eta}}^{\ensuremath{'}}{K}_{L}^{0}$, and ${B}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}{K}_{S}^{0}$. The data sample corresponds to the full BABAR dataset of $467\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ pairs produced at the PEP-II asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ …
