Contribution
It provides a comprehensive overview of the Standard Model's structure, emphasizing the role of gauge invariance and summarizing key experimental validations.
Findings
Electroweak precision tests confirm the Standard Model predictions.
Higgs boson searches support the electroweak symmetry breaking mechanism.
Neutrino oscillations indicate physics beyond the original Standard Model.
Abstract
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.
