Search for the Standard Model Higgs Boson at LEP /DELPHI Collaboration ; ALEPH Collaboration ; L3 Collaboration ; OPAL Collaboration
The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have collected 2461 pb−1 of e+e− collision data at centre-of-mass energies between 189 and 209 GeV, of which 536 pb−1 have energies above 206 GeV. The data have been used to search for the Standard Model Higgs boson. [...]

Precision Measurements of the b Forward-Backward Asymmetry at the Z Pole from LEP / Liebig, W (Wuppertal U.)
The four LEP experiments have measured the forward-backward asymmetry for the process e + e − → Z → b b at centre-of-mass energies close to mz with very high precision. Sophisticated techniques have been developed to reconstruct either the production flavour in exclusive final states like B → l ± , or the hemisphere charge on a large-size b-enriched sample. [...]
