Hydrodynamic response to jets with a source based on causal diffusion

Understand

We study the medium response to jet evolution in the quark-gluon plasma within the JETSCAPE framework.

• Recoil partons' medium response in the weakly coupled description is implemented in the multi-stage jet energy-loss model in the framework.
• As a further extension, the hydrodynamic description is rearranged to include in-medium jet transport based on a strong-coupling picture.
• To interface hydrodynamics with jet energy-loss models, the hydrodynamic source term is modeled by a causal formulation employing the relativistic diffusion equation.
