Description
Jet substructure techniques play a critical role in ATLAS in searches for new physics, are increasingly important in measurements of the Standard Model, and are being utilized in the trigger. To date, ATLAS has mostly focused on the use of calorimeter-based jet substructure, which works well for jets initiated by particles with low to moderate boost, but which lacks the angular resolution needed to resolve the desired substructure in the highly-boosted regime.
We present a novel approach designed to mitigate the calorimeter angular resolution limitations at a fundamental level, resulting in new objects. This approach provides superior performance compared to past methods for both jet mass and substructure variables.
