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

OUR FIT is obtained using the fit procedure and correlations as determined by the LEP Electroweak Working Group (see the note ``The ${{\mathit Z}}$ boson'' and ref. LEP-SLC 2006 ). For the ${{\mathit Z}}$ peak, we report the pole asymmetry defined by (3/4)$\mathit A_{{{\mathit e}}}\mathit A_{{{\mathit \tau}}}$ as determined by the nine-parameter fit to cross-section and lepton forward-backward asymmetry data.
