This lecture delves into the phenomenological applications of the standard model, focusing on key measurements used to verify the complex coupling structure with the W and Z bosons. The instructor discusses the verification of the standard model through various scattering experiments, emphasizing the importance of forward-backward asymmetry and the resolution of a two-fold ambiguity. The lecture also covers the LEP experiment at CERN, the tree-level superficial understanding of Z-bosons, and the concept of running couplings in quantum field theory. Additionally, the instructor explores the implications of minimal dark matter models and the renormalization group evolution in perturbation theory.
