Searching for new physics in top-pair and four-top production at the LHC

Friday March 11th, 14:30hs.

Speaker: Geraldine Servant

Abstract:

The top quark is expected to play a special role in electroweak symmetry breaking. It is therefore natural to use top quark observables to test the mechanism responsible for EW breaking and more generally to search for physics beyond the Standard Model.

In this talk, I will present observables involving top quark pair and double pair production that are useful probes of new physics at the LHC and I will discuss how much can be learnt from these events. Our predictions are particularly relevant for models of Higgs and Top compositeness.
