Data collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC are used to study the lifetime of the B0 and B+ mesons. The data sample consists of 7.4 fb-1 collected near the Y(4S) resonance. B0 and B+ mesons are fully…
We present a preliminary measurement of the time-dependent CP asymmetry for the neutral $B$-meson decay $B^0\to\phi K^0$. We use a sample of approximately 227 million $B$-meson pairs recorded at the $\Upsilon(4S)$ resonance with the BaBar…
We report a measurement of the time-dependent CP-asymmetry parameters $\cal S$ and $\cal C$ in color-suppressed $B^0 \to D^{(*)0} h^0$ decays, where $h^0$ is a $\pi^0$, $\eta$, or $\omega$ meson, and the $D^0$ decays to one of the CP…

We present branching fraction and CP asymmetry results for a variety of charmless B decays based on up to 124 fb^-1 collected by the BABAR experiment running near the Upsilon(4S) resonance at the PEP-II e+e- B-factory.
The BaBar experiment at SLAC is designed to measure CP violation in the B meson system, however the very high statistics combined with the different electron and positron beam energies, the detector design and the open trigger allow a wide…
As a followup to the latest BABAR amplitude analysis of the decay $B^+ \rightarrow K^+ K^- K^+$, we investigate the $K^+ K^-$ invariant-mass dependence of the CP asymmetry and compare it to that obtained by the LHCb collaboration. The…
