Measurement of Ab_FB using inclusive b-hadron decays
ALEPH Collaboration
Based on a sample of four million events collected by ALEPH from 1991 to 1995, a measurement of the forward-backward asymmetry in Z -> b-barb decays using inclusive final states is…
Study of the fragmentation of b quarks into B mesons at the Z peak
ALEPH Collaboration
The fragmentation of b quarks into B mesons is studied with four million hadronic Z decays collected by the ALEPH experiment during the years 1991-1995. A semi-exclusive reconstruc…
Observation of an Excess in the Search for the Standard Model Higgs Boson at ALEPH
ALEPH Collaboration
A search has been performed for the Standard Model Higgs boson in the data sample collected with the ALEPH detector at LEP, at centre-of-mass energies up to 209GeV. An excess of 3s…
Measurements of BR (b -> tau- nubar_tau X) and BR (b -> tau- nubar_tau D*+- X) and Upper Limits on BR (B- -> tau- nubar_tau) and BR (b -> s nu nubar)
ALEPH Collaboration
Inclusive branching ratios involving b to tau transitions are measured in approximately four million hadronic Z decays collected by the ALEPH detector at LEP. The fully-inclusive b…
Study of the CP asymmetry of B0 -> J/psi K0S decays in ALEPH
ALEPH Collaboration
The decay B0 -> J/psi K0_S is reconstructed with J/psi -> e+ e- or mu+ mu- and K0_S -> pi+ pi-. From the full ALEPH dataset at LEP1 of about 4 million hadronic Z decays, 23 candida…
Measurement of the Bbar0 and B- Meson Lifetimes
ALEPH Collaboration
The lifetimes of the Bbar0 and B- mesons are measured using a sample of about four million hadronic Z decays collected from 1991 to 1995 with the ALEPH detector at LEP. The data sa…
