Abstract
In theories that provide a mechanism for mass generation, we expect new physics to have a large coupling to the top quark. It is therefore natural to use top quark observables to test the mechanism responsible for electroweak symmetry breaking. In the first part of this paper, I discuss the production and decay of top partners at the LHC, stressing the theoretical motivations in the context of composite Higgs models. I then present an effective field theory approach to opposite and same sign top quark pair production and discuss the general model-independent constraints that can be obtained at the LHC on the restricted number of dimensionsix operators affecting t¯t and tt production.
