| | 5 | * Calculate analytically the cross section for %$e^+ e^- \to \mu^+ \mu^-$% as function of the CMS energy, including |
| | 6 | both exchange of a photon and a Z boson. Neglect masses of the external fermions. Compare your result with |
| | 7 | Software.MadGraph. |
| | 8 | * The Forward-Backward asymmetry is |
| | 9 | %$A_{FB}(\theta)=\frac{ d\sigma (\theta) - d\sigma(\pi-\theta)}{ d\sigma (\theta) + d\sigma(\pi-\theta)}$%. |
| | 10 | Plot it as a function of the CMS energy. |
