Among the Rarest: Theoretical Insights into Four Top-Quark Production at the LHC

If you have a question about this talk, please contact Terry Generet .

The production of four top quarks is one of the rarest processes in the Standard Model, and it was finally observed in 2023 at the LHC . Studying this process offers valuable insights into the top-Higgs interaction and may reveal new physics. Thus, comparing theoretical predictions with current and future measurements is a crucial test for the Standard Model.

In this talk, I will provide an overview of four top-quark production in proton-proton collisions and introduce the resummation framework used to achieve the most accurate QCD predictions to date for both the total cross section and invariant mass distribution. I will then present these results, highlighting their significance and the improvements made.

This talk is part of the HEP phenomenology joint Cavendish-DAMTP seminar series.
