$\boldsymbol A{}^{(0,{{\boldsymbol \mu}})}_{\boldsymbol FB}$ CHARGE ASYMMETRY IN ${{\boldsymbol e}^{+}}$ ${{\boldsymbol e}^{-}}$ $\rightarrow$ ${{\boldsymbol \mu}^{+}}{{\boldsymbol \mu}^{-}}$ 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)$\mathit A_{{{\mathit e}}}\mathit A_{{{\mathit \mu}}}$ as determined by the nine-parameter fit to cross-section and lepton forward-backward asymmetry data.

1  ABBIENDI 2001A error is almost entirely on account of statistics.
2  BARATE 2000C error is almost entirely on account of statistics.
3  ABREU 1995M perform this measurement using radiative muon-pair events associated with high-energy isolated photons.
4  ABE 1990I measurements in the range 50 ${}\leq{}$ $\sqrt {\mathit s }{}\leq{}$ $60.8$ GeV.
5  ABRAMS 1989D asymmetry includes both 9 ${{\mathit \mu}^{+}}{{\mathit \mu}^{-}}$ and 15 ${{\mathit \tau}^{+}}{{\mathit \tau}^{-}}$ events.
6  BACALA 1989 systematic error is about 5$\%$.
