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

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 .
