Titre  Exploring HighEnergy Physics with Jets (1/5) 
Résumé  This series of lectures is primarily associated with collider physics where one seeks to learn about fundamental interactions by colliding particles at high energy and by studying the products of these collisions. In this sense, talking about jets is essentially talking about the highlyenergetic quarks and gluons produced in these collisions and their dynamics governed by the strong interaction.This is ubiquitous in all recent colliders and jets are (to varying degrees) present in almost all aspects of collider phenomenology. This set of lectures is mostly twofolded: on one side it will try to give a taste of the broad range of aspects and applications of jet physics, on the other side it will show how it is rooted in (perturbative) Quantum Chromodynamics (QCD). Lecture 1/5  The concept of jets:Starting from elementary QCD aspects I will discuss key properties of the final state of e+e collisions (e.g. LEP). The goal here is to discuss basic properties of hadronic final states and to introduce the concept of jets. I will move to the case of protonproton collisions, discussing jet algorithms/definitions. I plan to discuss basic phenomenological applications as well as connections with fixedorder (amplitude) calculations and event simulations (Monte Carlo generators). Remarks:In terms of reference material, most of material covered in the lectures can be found in the set of Springer Lecture Notes "Looking Inside Jets: an introduction to jet substructure and boostedobject phenomenology" (arXiv:1901.10342). Some of the material covered in the first lecture can also be found in the review "Towards Jetography" (arXiv:0906.1833) as well as in standard QCD textbooks (e.g. "QCD and collider physics" by Keith Ellis, James Stirling and Brian Webber). The first and third lectures will be oriented towards concepts and phenomenological aspects. While keeping physics consequences as a target, lectures 2, 4 and 5 will focus more on calculations in the context of perturbative QCD. Note however that this is a tentative plan: I am happy to make adjustments if, in the course of the lectures, it appears that some aspects are worth exploring in more details or some different directions worth being introduced.
