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

The jet energy scale (JES) uncertainty is estimated using different methods at different p$_\text{T}$ ranges. In-situ techniques exploiting the p$_\text{T}$ balance between a jet and a reference object (e.g. Z or gamma) are used at lower p$_\text{T}$, but at very high p$_\text{T}$ (> 2.5 TeV) there is not enough statistics for such in-situ techniques. A low JES uncertainty at high-p$_\text{T}$ is important in several searches for new phenomena, e.g. the dijet resonance and angular searches. In the highest p$_\text{T}$ 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, and propagated to the final jet energy scale. This poster presents the JES uncertainty found with this method at sqrt(s) = 8 TeV and its developments.
