Bulk medium evolution has considerable effects on jet observables

Understand

We consider the case, in QCD, of a single jet propagating within a strongly interacting fluid, of finite extent.

• Interactions lead to the appearance of a source of energy-momentum within the fluid.
• The remnant jet that escapes the container is analyzed along with portions of the medium excited by the jet.
• We study the effect of a static versus a semi-realistic expanding medium, with jets traveling inward versus outward.
