Improved understanding of quantum chromodynamics (QCD) is crucial for advanced precision in LHC data analysis, as nearly all LHC collisions used in physics analysis contain jets of hadronic radiation produced by QCD. Jets are reconstructed using signals from the ATLAS inner tracking detector and calorimeters, and calibrated using in situ techniques. Differential cross-section measurements of jets and jet substructure are multi-faceted physics analyses that enable the testing of new theoretical predictions including both analytical calculations and parton shower Monte Carlos. In this seminar, I will present advancements made in hadronic object reconstruction and understanding made by ATLAS that are propelling our knowledge further than ever before.
