Gamma/Z interference in e+e- -> mu+ mu-
- Calculate analytically the cross section for $e+ e- \to \mu+ \mu-$ as function of the CMS energy, including both exchange of a photon and a Z boson. Neglect masses of the external fermions. Compare your result with MadGraph.
- The Forward-Backward asymmetry is $A_{FB}(\theta)=\frac{ d\sigma (\theta) - d\sigma(\pi-\theta)}{ d\sigma (\theta) + d\sigma(\pi-\theta)}$. Plot it as a function of the CMS energy.
