- Basic quantitative knowledge of the the physics of elementary particles and of their interactions, from the phenomenological and experimental point of view.
- Ability to estimate quantitatively processes and experiments.
- Knowledge of the time development of the main discoveries.
The language of the course is English. If all the students are italian I can switch to italian upon request.

Because of suspension on Sep 21 for the election day: FIRST LECTURE ON Tuesday September 22, 2020 @ 14.00We use the "quarto d'ora accademico" for the lecture starting time, so typically the actual starting time is about 10-15 min after the hour. We will adjust depending on what other lectures students have.
