Z Resonance: Cross Section Calculation

This lecture covers the calculation of the cross section for Z resonance in ete + 2 + utui interactions. It explains the Feynman rules for the relevant diagram, the vertex and propagator terms, and the use of helicity states. The lecture also discusses the Z boson decay rates, the Breit-Wigner resonance, and the forward-backward asymmetry in the differential cross section. Additionally, it explores the measurements of the Z line shape, the determination of the weak mixing angle, and precision tests of the standard model. The lecture concludes with insights into W+W- production, the W boson mass and width measurements, and the top quark properties.
