"Advances in Jet Physics at the LHC: Insights into Hadronic Final States and the Strong Interaction using ATLAS Run 2 Data"

Presented by Matthew LeBlanc

Monday, March 27, 2023, 3:00 pm — Small Seminar Room, Bldg. 510

Abstract: Improved understanding of quantum chromodynamics (QCD) is crucial for advanced precision in LHC data analysis: 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 higher-accuracy parton shower Monte Carlos. In this seminar, I will present advanced jet substructure reconstruction techniques that are poised to enhance jet performance in ATLAS during Run 3. I will also review the measurements made by ATLAS during LHC Run 2 that are pushing our knowledge of hadronic final states to unprecedented levels.
