We have measured the forward-backward asymmetry in Z 0→bb̄ decays using hadronic events containing muons and electrons. The data sample corresponds to 118 200 hadronic events at √s≈M z. From a fit to the single and dilepton p and p⊥ spectra, we determine A bb̄ = 0.130 -0.042+0.044 including the correction for B 0-B̄ 0 mixing.

Abstract
We have measured the forward-backward asymmetry in Z 0→bb̄ decays using hadronic events containing muons and electrons. The data sample corresponds to 118 200 hadronic events at √s≈M z. From a fit to the single and dilepton p and p⊥ spectra, we determine A bb̄ = 0.130 -0.042+0.044 including the correction for B 0-B̄ 0 mixing.File in questo prodotto:
