Interplay between hydrodynamics and jets

TL;DR

This paper explores how jet quenching interacts with hydrodynamic models of the medium in heavy-ion collisions, assessing the impact of jet energy loss on background evolution and observable signals.

Contribution

It combines JEWEL jet quenching simulations with realistic hydrodynamics to analyze the medium's response and the sensitivity of jet observables to medium details.

Findings

Effects on background are small at the event-averaged level.

Momentum transfer from jets significantly influences medium evolution.

Jet energy loss impacts observable signals subtly.

Abstract

By combining the jet quenching Monte Carlo JEWEL with a realistic hydrodynamic model for the background we investigate the sensitivity of jet observables to details of the medium model and quantify the influence of the energy and momentum lost by jets on the background evolution. On the level of event averaged source terms the effects are small and are caused mainly by the momentum transfer.
