Description

Hard scattered partons produced in collision of heavy ions are modified when propagating through the hot and dense medium of deconfined quarks and gluons known as the Quark Gluon Plasma. The study of jet substructure is an essential tool in quantifying this modification and in distinguishing between underlying mechanisms of parton-medium interactions. The latest CMS studies of jet substructure observables such as splitting function, groomed mass, boson-tagged fragmentation functions and jet shapes and their corresponding comparisons to theory give insight into the Quark Gluon Plasma, and how parton propagation is modified in QCD matter as opposed to matter.
