$\mathit A{}^{(0,{{\mathit \ell}})}_{\mathit FB}$ CHARGE ASYMMETRY IN ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \ell}^{+}}{{\mathit \ell}^{-}}$

INSPIRE   PDGID:
S044Z0L
For the ${{\mathit Z}}$ peak, we report the pole asymmetry defined by (3/4)$\mathit A{}^{2}_{{{\mathit \ell}}}$ as determined by the five-parameter fit to cross-section and lepton forward-backward asymmetry data assuming lepton universality. For details see the note “The ${{\mathit Z}}$ boson” and ref. LEP-SLC 2006 .

1  ABBIENDI 2001A error includes approximately 0.15 due to statistics, 0.06 due to event selection systematics, and 0.03 due to the theoretical uncertainty in $\mathit t$-channel prediction.
2  BARATE 2000C error includes approximately $0.15$ due to statistics, $0.04$ due to experimental systematics, and $0.02$ due to the theoretical uncertainty in ${{\mathit t}}$-channel prediction.
