Jet substructure observables are incisive probes of quantum chromodynamics (QCD), providing insight into perturbative and non-perturbative processes, and probing the structure and dynamics of the quark-gluon plasma (QGP). The jet shower is sensitive to multiple scales during its evolution, encoding the physics into correlated angular and momentum space phenomena which cannot be fully...
Jets are powerful probes used to improve our understanding of the strong force.
A useful way of understanding the radiation pattern of the jet is via the Lund jet plane, a representation of the phase space constructed using iterative Cambridge/Aachen declustering. In this talk, we discuss recent jet substructure measurements in pp and PbPb collisions based on Cambridge/Aachen declustering.
With the newly upgraded sPHENIX detector capable of performing high precision jet substructure measurements, we present a comprehensive and systematic jet substructure study at Relativistic Heavy Ion Collider. The study includes a variety of key jet substructure variables such as jet angularities with and without soft-drop or collinear-drop grooming, as well as recoil-free di-jet and...
The properties of partonic fragmentation in QCD depend on the flavors of the partons involved in the 1→2 splitting processes that drive parton showers. These dependencies arise from the differences in the Casimir factors of quarks and gluons, as well as the mass of heavy quarks. To explore these flavor dependencies, we use heavy-flavor jets as an experimental tool, particularly at low and...
