PHYSICS OF FUNDAMENTAL INTERACTIONS
Learning outcomes of the course unit
The first objective of the course is to illustrate the Standard Model of electroweak interactions, discussing its theoretical foundations and the main experimental verification of its validity. Interested students are required to have an elementary knowledge of quantum field theory and Feynman diagrams.
