Lecture
This lecture covers the decays of W and Z bosons, discussing their polarization states and wave-functions. It delves into the calculation of decay rates, matrix elements, lepton currents, and weak interactions. The lecture also explores the concept of electroweak unification, the weak hypercharge, and the couplings of gauge bosons. Additionally, it explains the Z boson, its couplings, decay modes, and branching ratios. Theoretical aspects of the standard model, gauge invariance, and the weak mixing angle are also addressed.
