Nuclear Particle Astrophysics (NPA) Seminar: Jesse Thaler, MIT, “Towards Systematic Jet Dissection”

Collisions at the Large Hadron Collider (LHC) are dominated by jets, collimated sprays of particles that arise from quantum chromodynamics (QCD) at high energies. With the remarkable performance of the LHC detectors, jets can now be characterized not just by their overall direction and energy but also by their substructure. At the same time, there has been substantial progress in predicting the properties of jets from first principles. In this talk, I highlight how these theoretical studies have pointed the way towards a systematic decomposition of jets into their substructure components, relevant not only for searches for new physics at the LHC but also for understanding the dynamics of QCD.
