Study of the decay $B ˉ^{0} \to I^_{c}^{+} p ˉ I ¨ ^{+} I ¨ ^{-}$ and its intermediate states

The Babar Collaboration, J. P. Lees, V. Poireau +351

We study the decay $B ˉ^{0} \to I^_{c}^{+} p ˉ I ¨ ^{+} I ¨ ^{-}$ , reconstructing the Î_{c}^{+} baryon in the $p K^{-} I ¨ ^{+}$ mode, using a data sample of $467\times 10^{6}…

Observation of the baryonic B decay B0bar --> Lambda_c^+ anti-Lambda K-

The BABAR Collaboration, J. P. Lees, V. Poireau +384

We report the observation of the baryonic B decay B0bar --> Lambda_c^+ anti-Lambda K- with a significance larger than 7 standard deviations based on 471x10^6$ BBbar pairs collected…

First evidence for $cos 2 I^^{2} > 0$ and resolution of the CKM Unitarity Triangle ambiguity by a time-dependent Dalitz plot analysis of $B^{0} \to D^{(*)} h^{0}$ with $D \to K_{S}^{0} I ¨ ^{+} I ¨ ^{-}$ decays

The BaBar, Belle Collaborations, : +422

We present first evidence that the cosine of the CP-violating weak phase $2 I^^{2}$ is positive, and hence exclude trigonometric multifold solutions of the CKM Unitarity Triangle using…

Search for $B^{-} \to I^ p ˉ I^½ I^ˉ ½$ with the BABAR experiment

The BABAR Collaboration, J. P. Lees, V. Poireau +235

We search for the rare flavor-changing neutral current process $B^{-} \to I^ p I^½ I^½$ using data from the BABAR experiment. A total of 424 fb $^{- 1}$ of $e^{+} e^{-}$ …

Branching fraction and form-factor shape measurements of exclusive charmless semileptonic B decays, and determination of |V_{ub}|

BABAR Collaboration, J. P. Lees, V. Poireau +361

We report the results of a study of the exclusive charmless semileptonic decays, B^0 --> pi^- l^+ nu, B^+ --> pi^0 l^+ nu, B^+ --> omega l^+ nu, B^+ --> eta l^+ nu and B^+ --> eta^…

Initial-State Radiation Measurement of the e+e- -> pi+pi-pi+pi- Cross Section

J. P. Lees, V. Poireau, V. Tisserand +383

We study the process e+e- -> pi+pi-pi+pi-gamma, with a photon emitted from the initial-state electron or positron, using 454.3 fb^-1 of data collected with the BABAR detector at SL…
