Relativity and Subatomic Physics

The course builds on the knowledge acquired in L1 and L2 to acquire the basics of special relativity (1/3 of the EU) and to offer students a brief introduction to subatomic particle physics (2/3 of the EU). It will thus allow to master an introduction to the description of the intimate structure of matter. After having developed the tools of special relativity necessary to the continuation of the course, we will detail both the study of atomic nuclei (nuclear physics) and that of "elementary" particles (subatomic physics proper). A first description of the standard model of particle physics and of the basic concepts of nuclear physics will be given.

This course is an introduction to acquire the basic notions necessary for the UE " Astroparticles experimental 1 " (HMPH210) of the second semester of the master CCP.

This course is based on the acquisition of the following concepts:

      - Introduction to Special Relativity 

     - Minkowski space-time and Lorentz-Poincaré transformations

     - Relativistic Mechanics

     - Energy-impulse quadrivectors and collisions between elementary particles

    - Atomic nucleus, binding energy

    - Nuclear instability and radioactive transformations

    - Model of the liquid drop

    - Low energy nuclear reactions

    - Effective interaction section

    - Notion of detection in subatomic physics

    - Notions of elementary particles

General training in physics at the L2 level

- Newtonian point mechanics.

- Mathematics for physics.
