Théorique, numérique
In recent years, we have developed a numerical program achieving resummed predictions for four-top production at hadron colliders. The choice to focus on such a process is driven by the fact that among all measurements to be made at the currently on-going LHC Run 3, those related to four-top production will be performed for the first time with enough precision to be compared with theoretical predictions. It is therefore critical to provide precise theoretical predictions. The proposed internship aims to make use of the program that has been developed at LPTHE, understand the underlying concepts (inherent to the theory of the strong interaction, i.e. QCD), and improve its efficiency so that it could be shared with the high-energy physics community as a whole.
