    55   * Calculate analytically the cross section for  $e^+ e^- \to \mu^+ \mu^-$ as function of the CMS energy, including
    66    both exchange of a photon and a Z boson. Neglect masses of the external fermions. Compare your result with
    7     Software.MadGraph.

    88   * The Forward-Backward asymmetry is
    99    $A_{FB}(\theta)=\frac{ d\sigma (\theta) - d\sigma(\pi-\theta)}{ d\sigma (\theta) + d\sigma(\pi-\theta)}$.
