Learning objectives
The aim is to provide some basic knowledge of nuclear and subnuclear
physics. The main properties that characterize nuclei, their constituents, the elementary particles
and interactions are illustrated. Selected topics are introduced by discussing the physical problems, the experimental approach, and the comparison beteween experimental data and predictions. The latters, in case of simple models are described in detail.

Analogies with other systems are also presented as well as the technologies and methods specific to subatomic physics. Topics of current research relevant for this subject are also briefly
illustrated.
Expected learning outcomes
At the end of this course, the students:
1) will acquire the main notions
that are the basis of the experiments and phenomenology that have
led to the description of the nuclei, their consituents, elementary particles and
their interactions at a fundamental level.
2) will know the
laws and properties of radioactive decays, fusion and fission
together with the mechanisms and the interactions that underline these
physical processes.
3) As to the structure of the nuclei, they will known the basic principles and
the relevant ingredients of the models describing the organization of
nucleons.
4) As far as elementary particles are concerned, they will be able to
identify the effects due to their constituents and to the symmetries of
the interactions which are at play during the formation and decay phases.
5) will be able to recognize the properties of the mediators of the
different forces, electromagnetic, strong and weak.

The knowledge gained by the students in this course is essential if one
wants to learn more on these subjects with other more advanced courses

Nuclear Physics:
- Properties of nuclei, stability valley.
- Weizsacker's semi-empiric formula.
- The Fermi Gas Model
- Alpha decay
- Beta decay and electron capture
- Gamma radiation
- The deuteron and nucleon-nucleon interaction.
- The shell model: magic numbers, spin-orbit coupling, magnetic moments.
- Nuclear fission and neutrino cross sections
- Nuclear fusion and reactions in the stars

Fundamental particles and interactions:
- Discrete simmetries (parity, charge conjugation, time reversal) and conservation
principles. Quantum numbers of states and parity violation.
- Matter and anti-matter.
- Classification of fundamental interactions, vector bosons.
- The physics of mesons and their interactions (strong, electromagnetic and weak).

Assessment methods and Criteria
The assessment is a mark resulting from an interview focusing on: 1-2 exercises from a pool of 10 selected by the student; general and methodological aspect of the subject; specific topics in both Nuclear and Particle Physics. Emphasis is given to the capability to master the concepts introduces by the course and to perform connections between the different topics presented during the lectures.
