Performance comparison of different top tagging techniques with the ATLAS detector

Searches for New Physics at the Large Hadron Collider push the search limits of heavy particles to higher and higher mass values. In a variety of cases these heavy particles can decay into final states containing top quarks, which can be highly energetic and boosted, such that the decay products merge in the detector. Reconstruction techniques using fat-jets, also known as top taggers, are then useful. In this talk, a performance comparison between different top taggers is presented.
