The Physics of the B Factories

This work is on the Physics of the B Factories. Part A of this book contains a brief description of the SLAC and KEK B Factories as well as their detectors, BaBar and Belle, and data taking related issues. Part B discusses tools and methods used by the experiments in order to obtain results. The results themselves can be found in Part C

Large detector systems for particle and astroparticle physics; Particle tracking detectors; Gaseous detectors; Calorimeters; Cherenkov detectors; Particle identification methods; Photon detectors for UV. visible and IR photons; Detector alignment and calibration methods; Detector cooling and thermo-stabilization; Detector design and construction technologies and materials. The LHCb experiment is dedicated to precision measurements of CP violation and rare decays of B hadrons at the Large Hadron Collider (LHC) at CERN (Geneva). The initial configuration and expected performance of the detector and associated systems. as established by test beam measurements and simulation studies. is described. © 2008 IOP Publishing Ltd and SISSA

Measurement of the B0→D*-Ds*+ and Ds+→ϕπ+ branching fractions

We present measurements of the branching fractions B(B0→D*-Ds*+) and B(Ds+→ϕπ+), based on 123×106 Υ(4S)→BB̅ decays collected by the BABAR detector at the PEP-II asymmetric-energy e+e-  B factory. A partial reconstruction technique is used to measure B(B0→D*-Ds*+) and the decay chain is fully reconstructed to measure the branching fraction product B(B0→D*-Ds*+)×B(Ds+→ϕπ+). Comparing these two measurements provides a model-independent determination of the Ds+→ϕπ+ branching fraction. We obtain B(B0→D*-Ds*+)=(1.88±0.09±0.17)% and B(Ds+→ϕπ+)=(4.81±0.52±0.38)%, where the first uncertainties are statistical and the second systematic
