We present an updated measurement of time-dependent CP-violating asymmetries in neutral B decays with the BABAR detector at the PEP-II asymmetric B Factory at SLAC. This result uses an additional sample of Upsilon(4S) decays collected in 2001, bringing the data available to 32 x 10(6) BB macro pairs. We select events in which one neutral B meson is fully(More)
We report on exclusive decays of B mesons into final states containing charmonium using data collected with the BABAR detector at the PEP-II storage rings. The charmonium states considered here are J/ψ , ψ(2S), and χ c1. Branching fractions for several exclusive final states, a measurement of the decay amplitudes for the B 0 → J/ψ K * decay, and(More)
The BABAR detector, situated at the SLAC PEP-II asymmetric e + e − collider, has been recording data at energies on and around the Υ (4S) resonance since May 1999. In this paper, we briefly describe the PEP-II B Factory and the BABAR detector. The performance presently achieved by the experiment in the areas of tracking, vertexing, calorimetry and particle(More)
We present measurements, based on a sample of approximately 23x10(6) BB pairs, of the branching fractions and a search for CP-violating charge asymmetries in charmless hadronic decays of B mesons into two-body final states of kaons and pions. We find the branching fractions B(B0-->pi(+)pi(-)) = (4.1+/-1.0+/-0.7)x10(-6), B(B0-->K+pi(-)) =(More)
A conceptual design of a mobile isocenter carbon ion gantry was carried out in the framework of the Particle Training Network for European Radiotherapy (PARTNER) and Union of Light Ion Centres in Europe (ULICE) projects. To validate the magnets used in this gantry, Finite Element Method (FEM) simulations were performed with COMSOL multiphysics; the purpose(More)
Data collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC are used to study the lifetimes of the B 0 and B + mesons. The data sample consists of 7.4 fb −1 collected near the Υ (4S) resonance. B 0 and B + mesons are fully reconstructed in several exclusive hadronic decay modes to charm and charmonium final states. The B lifetimes are(More)
We reconstruct the charmonium mesons J/ψ , ψ(2S) and χ c using a sample of 8.46 × 10 6 BB events collected by the BABAR detector operating at e + e − center of mass energies near the Υ (4S) resonance. By measuring rates relative to the branching fraction of the J/ψ , we obtain preliminary inclusive B branching fractions of (0.25 ± 0.02 ± 0.02)% to the ψ(2S)(More)
Using about 23M BB events collected in 1999-2000 with the BABAR detector, we report the observation of several hundred B → D (*) D (*) K decays with two completely reconstructed D mesons. The preliminary branching fractions of the low background decay modes B 0 → D * − D (*)0 K + are determined to be B(B 0 → D * − D 0 K +) = (2.8 ± 0.7 ± 0.5) × 10 −3 and(More)
Electron-positron annihilation data collected by the BABAR detector near the Υ(4S) resonance are used to study the inclusive decay of B mesons to D ± s and D * ± s mesons, where the D ± s is reconstructed using the decay D ± s → φπ ±. The production fraction of inclusive D (*)± s and the corresponding momentum spectra have been determined. The exclusive(More)
