The Standard Model of Electroweak Interactions

Understand

Gauge invariance is a powerful tool to determine the dynamical forces among the fundamental constituents of matter.

• The particle content, structure and symmetries of the Standard Model Lagrangian are discussed.
• Special emphasis is given to the many phenomenological tests which have established this theoretical framework as the Standard Theory of the electroweak interactions: electroweak precision tests, Higgs searches, quark mixing, neutrino oscillations.
• The present experimental status is summarized.
