Note from June 29, 2020
Although we do not yet know how long the social distancing related to the Covid-19 pandemic will last, and regardless of the changes that had to be made in the evaluation of the June 2020 session in relation to what is provided for in this learning unit description, new learnig unit evaluation methods may still be adopted by the teachers; details of these methods have been - or will be - communicated to the students by the teachers, as soon as possible.

a. Contribution of the teaching unit to the learning outcomes of the programme (PHYS2M and PHYS2M1) AA1 : A1.1, A1.2, A1.6 AA2 : A2.1, A2.5 AA3 : A3.1, A3.2, A3.3, A3.4 AA4 : A4.1, A4.2 AA5 : A5.1, A5.2, A5.3, A5.4 AA6 : A6.1, A6.2 AA7 : A7.1, A7.3, A7.4 AA8 : A8.1 b. Specific learning outcomes of the teaching unit By the end of this teaching unit, the student will be able to : 1. implement renormalised perturbation theory of theories with quantum scalar and spinorial fields, possibly even vector and gauge fields ; 2. understand the roles of regularization and of renormalization points in a perturbative renormalization scheme ; 3. explain the occurrence of masses and interaction coupling constants which are running functions of renormalization scales ; 4. further the study of a specific topic of advanced quantum field theory ; 5. relate the contents of the course to current developments in quantum field theory at the interface of the fundamental quantum interactions and of the gravitational interaction. |
