Description
High-energy nuclear collisions offer a captivating glimpse into the creation and evolution of strongly coupled plasmas. Within these collisions, droplets of the quark-gluon plasma (QGP), a state of matter believed to have permeated the early universe, are generated. These droplets of the QGP quickly expand but their flow is azimuthal anisotropic and thus these processes offer insight into the dynamics interactions between the evolution of the plasma and the evolution of jets that probe the plasma. In this talk, I'll discuss the use of anisotropic jet substructure observables as a means of investigating anisotropically flowing matter. Using Soft-Collinear Effective Theory, we explicitly calculate the jet functions associated with these observables and apply them to p-p and A-A collisions. We demonstrate the fidelity of our formalism in p-p collisions by comparing each observable with experimental measurements at the LHC for the isotropic case. By introducing a model for the anisotropic flow, we demonstrate that each of these observables can serve as a novel probe of a strongly coupled flowing matter.
