Lepton and quark asymmetries
Vitaliano Ciulli
Lepton and quark asymmetries at Z boson peak are a powerful means to test the couplings of the Z boson to fermions. The measurements performed at LEP and SLC colliders are reviewed…
AFB(b) Status of Results
Vitaliano Ciulli
The status of results on forward-backward asymmetry in Z -> bbbar decays is reviewed. A comparison of LEP measurements, with emphasis on the final ALEPH measurement with leptons, a…
Studies of b-quark fragmentation
V. Ciulli
I will review new studies of b-quark fragmentation performed at the Z peak by ALEPH and SLD. An improved sensitivity to distinguish between fragmentation model and more accurate me…
Spectroscopy of excited b and c states
Vitaliano Ciulli
Recent results on the spectroscopy of excited b and c states are presented. In particular, these include the first observation of the D_1 (light quark spin j=1/2) resonance, search…
