Abstract
Résumé

To present knowledge, all the physics at the Large Hadron Collider (LHC) can be described in the framework of the Standard Model (SM) of particle physics. Indeed the newly discovered Higgs boson with a mass close to 125 GeV seems to confirm the predictions of the SM. Thus, besides looking for direct manifestations of the physics beyond the SM, one of the primary missions of the LHC is to perform ever more stringent tests of the SM. This requires not only improved theoretical developments to produce testable predictions and provide experiments with reliable event generators, but also sophisticated analyses techniques to overcome the formidable experimental environment of the LHC and perform precision measurements. The present article proposes an overview of the present theoretical tools and of the experimental results in the field of strong and electroweak interactions.

À ce jour, l'ensemble de la physique du Grand collisionneur de hadrons LHC s'inscrit dans le cadre du modèle standard (MS) de la physique des particules. Ainsi la découverte récente du boson de Higgs avec une masse proche de 125 GeV confirme-t-elle une prédiction centrale du MS. L'une des missions principales du LHC, avec la recherche de manifestations directes de nouvelle physique au-delà du MS, consiste à soumettre le MS à des tests toujours plus contraignants. Cela requiert non seulement des outils théoriques toujours plus performants permettant des prédictions vérifiables et fournissant aux expériences des générateurs d'événements fiables, mais aussi des techniques d'analyse des données sophistiquées pour surmonter les conditions dantesques de l'environnement expérimental au LHC et permettre des mesures de précision. Cet article propose une vue d'ensemble des outils théoriques disponibles et des résultats expérimentaux récents dans le domaine des interactions fortes et électrofaibles.
