TL;DR
This paper discusses using top quark measurements at colliders as a model-independent way to search for or constrain heavy new physics beyond the Standard Model, leveraging effective field theory techniques.
Contribution
It introduces an effective field theory approach to probe heavy new physics through top quark interactions in a model-independent manner.
Findings
Effective field theory constrains new physics scenarios.
Top quark measurements can reveal deviations from the Standard Model.
Method quantifies the parameter space for new physics if no deviations are observed.
Abstract
The heaviest fermion is expected to couple strongly to new physics and appears therefore as a natural probe in many BSM scenarios. Moreover, top physics has now entered in a precision era thanks to the huge amount of top quarks produced at hadron colliders, advanced experimental methods and accurate theoretical predictions. In this talk, we will used effective field theory to search for heavy new physics in a model independent way. This method can also be used to quantify the room left for new physics if no deviation from the SM is found.
