The exam consists of a presentation that the student gives, where they discuss one measurement in particle physics; or illustrate one aspect of the phenomenology identifyins also the main experimental results to study it. Students can start from a single article or work out a synthesis of multiple results. Describing an experimental result is always required, also of theorists. The exam continues with questions on the presentation and, then, moving on to any other topic within the scope of the course, to probe how well the student masters the subject and to check their ability to inter-connect several aspects of particle physics.
