A Measurement of the Branching Fractions of exclusive Bbar -> D(*)(pi)l-nubar Decays in Events with a Fully Reconstructed B Meson

The BABAR Collaboration, B. Aubert

We report a measurement of the branching fractions for Bbar -> D(*)(pi)l-nubar decays based on 341.1 fb-1 of data collected at the Upsilon(4S) resonance with the babar detector at…

Time-dependent Dalitz plot analysis of B0 -> D-(+) K0 Pi+(-) decays

The BABAR Collaboration, B. Aubert

We present for the first time a measurement of the weak phase 2b+g obtained from a time-dependent Dalitz plot analysis of B^0 -> D-(+) K0 Pi+(-) decays. Using a sample of approxima…

First Flavor-Tagged Determination of Bounds on Mixing-Induced CP Violation in Bs -> J/psi phi Decays

CDF Collaboration, T. Aaltonen

This Letter describes the first determination of bounds on the CP-violation parameter 2*beta_s using Bs decays in which the flavor of the bottom meson at production is identified.…

Measurement of D0-anti-D0 Mixing using the Ratio of Lifetimes for the Decays D0 --> K-pi+, K-K+, and pi-pi+

The BABAR Collaboration, B. Aubert

We present a measurement of - mixing parameters using the ratios of lifetimes extracted from a sample of mesons produced through the process $D^{*+}\to\D^0π^+…

Study of B0 --> l+l'- decays (l,l' = e,mu)

The BaBar Collaboration, B. Aubert

We present a search for the decays B0 --> e+e-, B0 --> mu+ mu- and B0 --> e mu using data collected with the BABAR detector at the PEP-II e+e-collider at SLAC. Using a dataset corr…
