Description
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.
