FACTORIZATION OF THE CHARGE CORRELATION FUNCTION IN $B^0 {\bar B}^0$ OSCILLATIONS

Measurement of B0-B-0 flavor oscillations in hadronic B0 decays.

Flavor oscillations of neutral B mesons have been studied in e+e- annihilation data collected with the BABAR detector at center-of-mass energies near the upsilon(4S) resonance. The data sample used for this purpose consists of events in which one B0 meson is reconstructed in a hadronic decay mode, while the flavor of the recoiling B0 is determined with a tagging algorithm that exploits the corr...

Search for CP violation in B0-B0 mixing using partial reconstruction of B0→D*- Xℓ+ νℓ and a kaon tag.

We present results of a search for CP violation in B0- B0 mixing with the BABAR detector. We select a sample of B0→D*- Xℓ+ ν decays with a partial reconstruction method and use kaon tagging to assess the flavor of the other B meson in the event. We determine the CP violating asymmetry ACP≡[N(B0B0)-N(B0B0)]/[N(B0B0)+N(B0B0)]=(0.06±0.17(-0.32)(+0.38))%, corresponding to ΔCP=1-|q/p|=(0.29±0.84(-1....

Search for T, CP, and CPT violation in B0-B0 mixing with inclusive dilepton events.

We report the results of a search for T, CP, CPT, and violation in B0-B0 mixing using an inclusive dilepton sample collected by the BABAR experiment at the PEP-II factory. Using a sample of 232 x 10(6) BB pairs, we measure the T and CP violation parameter |q/p| - 1 = (-0.8 +/- 2.7(stat) +/- 1.9(syst) x 10(-3), and the CPT and CP parameters Imz = (13.9 +/- 7.3(stat) +/- 3.2(syst)) x 10(-3) and D...

Penguin corrections and strong phases in a time-dependent analysis of B0(B0) → π+π−

From a time-dependent analysis of the decay (−) B d → π+π− and using a model-dependent AP/AT ratio of the penguin-to-tree amplitudes contributing to the decay, both the weak phase α and the strong phase shift difference δ can be extracted from the data. The value of the weak phase β, expected to be measured from the decay B d → J/ψK S , is used to parameterize the value of AP/AT and the corresp...
