Direct Measurement of A b at the Z 0 Pole Using a Lepton Tag ∗
We present a direct measurement of the parity violation parameter A b , derived from the left-right forward-backward asymmetry of b quarks tagged via leptons from semileptonic decays. The lepton identification algorithm combines information from tracking, calorimetry and from the SLD Cherenkov Ring Imaging Detector. The value of A b is extracted using a maximum likelihood fit to the differentia...
متن کاملMeasurement of the Direct CP Asymmetry in  ̄BâƒTMXs+dÎ3 Decays with a Lepton Tag
We report the measurement of the direct CP asymmetry in the radiative B̄ → Xs+dγ decay using a data sample of (772 ± 11) × 10 BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy ee collider. The CP asymmetry is measured as a function of the photon energy threshold. For E∗ γ ≥ 2.1 GeV, where E ∗ γ is the photon energy in the center-of-mass frame, we obt...
متن کاملImproved Direct Measurement of A b and A c at the Z 0 Pole Using a Lepton Tag
The parity violation parameters A b and A c of the Zbb and Zc¯ c couplings have been measured directly, using the polar angle dependence of the polarized cross sections at the Z 0 pole. Bottom and charmed hadrons were tagged via their semileptonic decays. Both the electron and muon analyses take advantage of new multivariate techniques to increase the analyzing power. Based on the 1993-98 SLD s...
