After the discovery of the Higgs boson in ATLAS and CMS collaborations, the standard model is complete. However, there are still remaining questions that the standard model cannot explain such as dark matter, etc. To understand these phenomena, we need to understand the property of this new particle and extend the standard model. Vector-like quark is one of the new candidates that will extend...

One of the most challenging problems of the Standard Model (SM) is the mass of the Higgs boson that diverges by taking the loop contributions into account. The decay of new particles like Vector-Like Quarks (VLQs) could be an interesting explanation as the final state in SM particles is well understood. We will present here the decay of a VLQ T' in a quark top and a Higgs boson in a dileptonic...

Mon projet de recherche est réalisé au sein de l’experience internationale CMS, qui analyse les collisions proton-proton de haute énergie produites par le LHC. Le projet est centré sur la recherche de particules lourdes, chargées et à long temps de vie (HSCP: Heavy Stable Charged Particles) prédites par certains modèles au delà du Modele Standard. Une premiere partie consiste à analyser les...

The Standard Model (SM) is unable to explain the predominance of matter over antimatter in our present universe. Matter and antimatter are linked by a CP-symmetry transformation, and current explanations involve a new source of CP symmetry breaking. An effective field theory (EFT) will be used to describe CP-symmetry violation, which will be searched for by analyzing the production and decay...

Even if the interest into studying charged leptons is not new, it has been growing over the past few years. This is mainly because of the lack of new physics signal at the LHC, and the potential signal of the g-2 experiment at FermiLab. Technical advances giving access to the study of the tau lepton at the LHC along with Belle II, and the possibility to produce high intensity pulsed muon...

In the framework of the ATLAS Run-3 datataking period, an early-data analysis targeting emerging jets is in preparation. This analysis is the first effort to study this signature in the ATLAS collaboration.

Emerging jets are part of a global Beyond the Standard Model (BSM) theory called Dark QCD. This BSM theory predicts the existence of a new dark sector : containing QCD-like particles and...
