Abstract

This lecture series is devoted to the Basic structure of the Standard Model, relevant for ist extensions proposed to solve the hierarchy problem. The following topics are discussed: spontaneous global symmetry breaking, the physics of the Nambu- Goldstone bosons, the Higgs mechanism, Standard Model as a renormalizable but effective theory and radiative corrections to the scalar potential (Coleman-Weinberg one loop formula). Furthermore, equipped with those tools, two main scenarios for BSM physics: supersymmetric models and the Higgs boson as a pseudo-Goldstone boson, are briefly reviewed.
