The evolution of boosted top tagging at the LHC
- Jennifer Roloff
- Matt LeBlanc
- Loukas Gouskos
Description
In this module, we start with an executive summary of jet physics and its importance for the LHC physics program, followed by an overview of the particle tagging techniques developed by the ATLAS and CMS experiments, focusing on the case of boosted, hadronically decaying top quarks. The evolution of ML architectures used for boosted object tagging will be surveyed, beginning from cut-based taggers based on engineered features and proceeding through feature-based networks to the point-cloud, image- and graph-based approaches that are being used in ATLAS and CMS results today.
