Jennifer Roloff - Exploring quantum chromodynamics with jets at the LHC

Jets are a central component of many analyses at collider experiments. Despite their pervasiveness, their production involves both perturbative and non-perturbative aspects of QCD, resulting in a rich inner structure (substructure) that is challenging to model. The talk will explore how jet reconstruction connects to our understanding of jet modeling, and examine how experimental methods can be used to improve the precision of jet reconstruction. This will be followed by a discussion of how measurements of jet substructure observables such as the Lund jet plane can be used to create novel tests of parton showers and hadronization, feeding back into a more rigorous understanding of jet formation. The talk will conclude by addressing future applications of this work at the LHC and beyond.
