Titre  Effective field theories in particle physics (1/4) 
Résumé  The methods and ideas of Effective Field Theory (EFT) are among the most powerful and deep organising principles in physics, and particularly so in Quantum Field Theory and its ramifications and applications into particle physics, condensed matter physics, and statistical mechanics. \par The basic idea is to approximate a physical system by integrating out the degrees of freedom that are not relevant in a given experimental setting. These are traded for a set of effective interactions between the remaining degrees of freedom. \par In these lectures we will review the concept, techniques, and applications of the EFT framework. \\  Overview of the EFT landscape : Prominent examples including Fermi theory, the HeisenbergEuler Lagrangian, and chiral perturbation theory. \\  Integrating out heavy particles : Quantitative discussion of the procedure in a quantum field theory. Explicit example of the tree and oneloop level matching between an EFT and its UV completion. \\  Beyond the Standard Model : Introduction of the Standard Model EFT by extending the Standard Model Lagrangian with nonrenormalizable interactions representing the effects of new heavy particles. \\  Functional integration methods and EFTs for classical systems.
