Beschreibung:
These lectures are meant to be a reference and handbookfor an introductory course in Theoretical ParticlePhysics, suitable for advanced undergraduates or beginning graduatestudents. Their purpose is to reconcile theoretical rigourand completeness with a careful analysis of more phenomenologicalaspects of the physics. They aim at filling the gapbetween quantum field theory textbooks and purelyphenomenological treatments of fundamental interactions.
