چکیده
The charmless semileptonic decay B branching fraction has been measured, using inclusive techniques, by the Aleph, Delphi and L3 experiments at LEP. The average of their results is BR(b → Xuℓ¯ ν) = (1.74 ± 0.37 (stat.+exp.) ± 0.38 (b → c) ± 0.21 (b → u)) × 10 −3 .

متن کاملInclusive Charge Flow Measurements of the Effective Mixing Angle
The LEP results for the eeective mixing angle sin 2 lept ef f from measurements of the inclusive charge ow in hadronic Z decays are presented. Using the very precise LEP data on exclusive and inclusive particle spectra to constrain the predictions of hadronization models systematic uncertainties have been reduced. The combined LEP result is sin 2 lept ef f = 0:2320 0:0010.
متن کاملb-HADRON PHYSICS AT LEP
Modelling the fragmentation process in Monte Carlo is a source of systematic error to many LEP b-physics analyses e.g. |Vub|. Constraining this error from data measurements is therefore important and in the last few years precise measurements have begun to appear e.g. from ALEPH1 using the semi-exclusive reconstruction of B → Dlν̄l a decays and from SLD2 using a fully inclusive approach. The fra...
متن کاملRecent Results from LEP and Comparisons with Υ(4S) Experiments
Semileptonic (s.l.) B decays represent a favorable laboratory to study the dynamics of heavy quark decays, to determine the size of the |Vub| and |Vcb| CKM mixing matrix elements, crucial in the unitarity triangle test of the Standard Model, and to acquire informations on the structure of the B meson itself. The Aleph, Delphi, L3 and Opal experiments have analyzed together about 1.5 M s.l. B de...
