Measurement of CP asymmetry in [beta] --> [sigma] [gamma] decays using a sum of exclusive final states
… by the BABAR detector at the PEP-II asymmetric B factory and reconstruct sixteen flavor-specific B decay modes containing a high energy photon and a hadronic Xs system. We measure the CP asymmetry to be -0.011 ± 0.030stat ± 0.014syst for a photon energy threshold at 1.6 GeV and the hadronic system …

Electron Identification and Measurement of the Inclusive Semileptonic Branching Fraction of B Mesons at the BABAR Experiment
… am asymmetrischen Speicherring PEP-II ("B-Factory") aufgezeichnet wurden. Das Volumen der analysierten Daten entspricht einer integrierten Luminosität von 4.13 1/fb auf der Y(4S) Resonanz und 0.97 1/fb bei einer um 40 MeV verringerten Schwerpunktsenergie. B - Anti-B Ereignisse werden …

Bottomonium Spectroscopy at Belle: Studies of Radiative and Hadronic Transitions
… energy physics experiment located at the KEKB B-Factory epem collider, based at KEK in Tsukuba, Japan. Belle has accumulated a large dataset near the FourS and ThreeS resonances, collectively containing more than 28 million ThreeS and 556 million FourS. Some of these decay to other bbbar …

Precision Measurement of the Mass Difference of Neutral and Charged B Mesons
This work presents a precision determination of the mass difference of neutral and charged B mesons, m(B0) - m(B+). The measurement is based on a data sample of about 232 million B-meson pairs recorded with the BABAR detector at the e+e- storage-ring system PEP-II. In events of e+e- --> …
