Hadronic Jets: Accuracy and Precision of their Reconstruction and Calibration in ATLAS — •Christopher Young — University of Freiburg, Freiburg im Breisgau, Germany

Hadronic jets are prolifically produced in LHC collisions such that their reconstruction is essential for understanding many different physics processes. This talk will detail how such jets are precisely reconstructed in the ATLAS detector using a particle flow algorithm developed for the high pile-up environment of Run 2 of the LHC and beyond. Additionally the accuracy of the calibration of the energy scale of hadronic jets is a leading source of experimental systematic uncertainty in many searches and measurements. The derivation of the latest calibration using data, and the accuracy and understanding achieved will also be covered.
