Educational objectives
The main expected results, at the end of the course, for the knowledge and the capacity of undestanding are:

- Knowledge of the particle physics phenomenology and of the main experimental methods used
- Knowledge of fundamental interactions, particle classificarion and their properties, in the framework of the Standard Model
- Capacity of contextualize the main aspects of the vaste phenomenology of elementary processes within the Standard Model.

For the capacity of applying knowledge and understanding, the expected results are:

- Capacity of analyzing teh acquired knowledges with a critical approach and in a transversal way.
Prerequisites
The course, intended for all the curricula, has a phenomenological approach. Topics will be addressed starting with a brief introduction of the theory; focus will be mainly on experimental aspects, interpretation of the data and comparison with theory. It is therefore fundamental to have knowledge of the underlying theory, which is the subject of the course "Theoretical Physics", with some specific topics, such as QED and Feynman diagrams. It is also assumed that students have knowledge of elementary scattering theory, electromagnetic structure of nucleons and nuclei and proton structure models. It is useful to have basics of group theory.
Teaching methods
Lectures.
Other information
The department and the associated reseach insitutes organize seminars on the research activities in the department and also on other relevant aspects of Particle Physics. The student is advised to attend the seminars.
Learning verification modality
The exams is an oral proof and consits of an interview of about 1 hour. The first part of the exam concerns the discussion of a fundamental discovery (or measurement) in Particle Physics; the paper describing the discovery, or the measurement, is assigned to the student few days before the foreseen date of the examination. In the second part, the student will be asked to discuss other topics of the programme. The student is evaluated on his capacity of understanding and interpreting the article content, on the knowledge of the arguments of the programme and on the ability of putting different topics in relation among them. It is appreciated the capacity to examine in a critical way the process that led to the present model of Elementary Particle Physics.
