Testing the EFT paradigm with top quark final states in proton-proton collisions at LHC with ATLAS and CMS

TL;DR

This paper reviews recent top quark analyses at the LHC by ATLAS and CMS, using effective field theories to interpret potential indirect signs of new physics at high energy scales.

Contribution

It provides an overview of how EFT frameworks are applied in top quark measurements to search for physics beyond the Standard Model.

Findings

No direct new physics signals observed.

Constraints placed on EFT operators affecting top quark interactions.

Enhanced sensitivity of top quark measurements to potential new physics.

Abstract

With the absence of the direct detection of new physics and the large data set collected at the LHC, the search for indirect effects in precision measurements became popular. Effective field theories enable to interpret these effects that originate from physics manifested at currently unreachable energy scales in a model independent framework. In this report, an overview of new analyses performed by the ATLAS and CMS Collaborations in the field of top quark physics is given.
