EXPERIMENTAL PHYSICS OF FUNDAMENTAL INTERACTIONS
(objectives)
The course provides the notions of experimental physics of elementary particles. The course deals with both experimental and theoretical topics whose aim is to allow students to understand the experimental and theoretical path that led to the formulation of the Standard Model of fundamental interactions as we know it today. The fundamental experiments and discoveries starting from the discovery of elementary particles in cosmic rays up to the production of the vector bosons W and Z and of the Higgs boson are illustrated in detail. At the end of the course the student will have a broad view of particle physics from an experimental point of view, and sufficient knowledge of the theoretical tools necessary to understand its mechanisms.
The course is supported by an exercise section whose aim is to reinforce the level of understanding of the topics covered and the calculation methods of the elementary processes, as well as allow students to apply the techniques learned for the calculation of some processes and the relationships between they exist. The course is aimed at all students and those who undertake a path of elementary particle physics that not, providing the basics of physics of elementary particles
