Towards a quantitative understanding of high $p_T$ flow harmonics

TL;DR

This paper reviews recent progress in modeling high transverse momentum flow harmonics by coupling jet energy loss models with event-by-event viscous hydrodynamics, successfully describing key experimental data and revealing correlations between soft and hard observables.

Contribution

It introduces a framework combining jet energy loss with viscous hydrodynamics to quantitatively analyze high $p_T$ flow harmonics and their correlation with soft flow.

Findings

Framework describes $R_{AA}$, $v_2$, $v_3$ at high $p_T$

High $p_T$ $v_2$ correlates linearly with soft $v_2$

Enables new soft-hard observable correlations in heavy ion collisions

Abstract

In this proceedings I briefly review the recent progress achieved on the calculation of $v_n$ at high $p_T$ via the coupling of a jet energy loss model with full event-by-event viscous hydrodynamics. It is shown that that this framework can simultaneously describe experimental data for $R_{AA}$, $v_2$, and $v_3$ at high $p_T$. High $p_T$ $v_2$ is found to be approximately linearly correlated with the soft $v_2$ on an event-by-event basis, which opens up a new way to correlate soft and hard observables in heavy ion collisions.
