Measurement of the CP-Violating Asymmetry Amplitude sin2$\beta$ (2002)

Aubert, B., Boutigny, D., Gaillard, J.M., Hicheur, A., Karyotakis, Y., Lees, J.P., ...

We present results on time-dependent CP-violating asymmetries in neutral B decays to several CP eigenstates. The measurements use a data sample of about 88 million Y(4S) --> B Bbar decays collected...

Measurement of the Branching Fraction and CP Content for the Decay $B^0 \to D^{*+}D^{*-}$ (2002)

Aubert, B., Boutigny, D., Gaillard, J.M., Hicheur, A., Karyotakis, Y., Lees, J.P., ...

We report a measurement of the branching fraction of the decay B^0 --> D^{*+} D^{*-} and of the CP-odd component of its final state using the BaBar detector. With data corresponding to an integrated...

Measurement of the $B^0$ lifetime with partially reconstructed $B^0 \to D^{*-}l^+\nu_l$ decays (2002)

Aubert, B., Boutigny, D., Gaillard, J.M., Hicheur, A., Karyotakis, Y., Lees, J.P., ...

The B0 lifetime has been measured with a sample of 23 million BBbar pairs collected by the BaBar detector at the PEP-II e+e- storage ring during 1999 and 2000. Events from the semileptonic decay B0...

Search for T and CP violation in $B^0-\bar B^0$ mixing with inclusive dilepton events (2002)

Aubert, B., Boutigny, D., Gaillard, J.M., Hicheur, A., Karyotakis, Y., Lees, J.P., ...

We report the results of a search for T and CP violation in B0-anti-B0 mixing using an inclusive dilepton sample collected by the BaBar experiment at the PEP-II B Factory. The asymmetry between...

Penguin Mediated B Decays at BABAR (2002)

Aubert, B., Boutigny, D., Gaillard, J.M., Hicheur, A., Karyotakis, Y., Lees, J.P., ...

We report on preliminary results of searches for penguin mediated B decays based on 20.7 fb^{-1} of data collected at the Y(4S) peak with the BABAR detector at PEP-II. The following branching...
