Prerequisites
No prerequisites for students who have obtained a Bachelor's degree in physics and who therefore already have a basic knowledge of classical gravitation (GN), relativistic mechanics (c),quantum mechanics (h) and, ideally, relativistic gravitation (GN+ c).
Main themes
Introduction to the concept of unification based on gauge invariance and description of the sometimes surprising rules governing our universe both at the microscopic level (' 10-20 m) and at the macroscopic level (' 10+26 m), through the interactions of its content in matter and energy, namely: ordinary matter, antimatter, extraordinary matter, dark matter and dark energy.
Introduction to the major experiments that led not only to the construction of the Standard Model but also to its validation and discussion of the difficulties encountered in their achievements
Aims
At the end of this learning unit, the student is able to : | |

a. Contribution of the teaching unit to the learning outcomes of the programme (PHYS2M and PHYS2M1) AA1: A1.1, A1.4 AA3: A3.1 AA5: A5.3 AA7: A7.2 b. Specific learning outcomes of the teaching unit At the end of this teaching unit, the student will be able to: 1. formulate the theoretical concepts associated with fundamental interactions (including gravitation) by highlighting a unifying principle, gauge invariance and a separating mechanism, symmetry breaking ; 2. present the great experiments at the base of the Standard Model describing the fundamental interactions (strong, weak and electromagnetic) between the elementary particles (quarks, leptons and bosons of gauges, Higgs boson) ; 3. integrate experimental and data analysis techniques used in modern experiments in particle physics. |
Content
1) Theoretical and experimental introductions to fundamental interactions
a) long-range (electromagnetism and gravitation) : from classical potentials to relativistic fields ;
b) short range (subnuclear) : from confinement (gluons) to spontaneous break (W, Z and h bosons) ;
and the properties distinguishing them in processes involving the constituents of matter (quarks and leptons) :

b) short range (subnuclear) : from confinement (gluons) to spontaneous break (W, Z and h bosons) ;
and the properties distinguishing them in processes involving the constituents of matter (quarks and leptons) :
- conservation of baryonic and leptonic numbers ;
- Zweig rule in hadron transitions ;
- preservation of flavor in neutral currents ;
- violation of flavor in charged currents ;
- violation of invariance under spatial and temporal inversion.
Teaching methods
Due to the COVID-19 crisis, the information in this section is particularly likely to change.
Lectures (presentation on the blackboard and projection of transparencies).Integrative project.
Practice sessions on analysis of LHC events.
Evaluation methods
Due to the COVID-19 crisis, the information in this section is particularly likely to change.
- Oral exam on the whole teaching unit during the exam session.
- Preparation of a question of your choice to present orally (either during the examination or during presentation sessions that will eventually be scheduled at the end of the semester).
- A "laboratory" report (on the observation of the W and Z bosons at the LHC) and / or a more theoretical project report, to be defended orally.
Other information
Following the sanitary conditions, the modalities of the teaching AND the examination could be reassessed according to the situation and the rules in force.
