The Standard Model of Electroweak Interactions

Abstract

Gauge invariance is a powerful tool to determine the dynamics of the electroweak and strong forces. 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 electroweak interactions.Comment: Lectures given at the 2004 European School of High-Energy Physics, Sant Feliu de Guixols, Spain, 31 May - 11 June 2004 47 pages, 35 figure
