High-pT Jet Energy Scale Uncertainty from single hadron response with the ATLAS detector

Poulsen, Trine LU (2016) Fourth Annual Large Hadron Collider Physics Conference (LHCP2016) In PoS - Proceedings of Science
Abstract
The jet energy scale (JES) uncertainty is estimated using different methods at different pT ranges. In-situ techniques exploiting the pT balance between a jet and a reference object (e.g. Z or gamma) are used at lower pT, but at very high pT (> 2.5 TeV) there is not enough statistics for such in-situ techniques. A low JES uncertainty at high-pT is important in several searches for new phenomena, e.g. the dijet resonance and angular searches. In the highest pT range, the JES uncertainty is estimated using the calorimeter response to single hadrons. In this method, jets are treated as a superposition of energy depositions of single particles. An uncertainty is applied to each energy deposition belonging to the particles within the jet,... (More)

An uncertainty is applied to each energy deposition belonging to the particles within the jet, and propagated to the final jet energy scale.
