Stimulation of static deconfined medium by multiple hard partons

TL;DR

This paper studies how a static deconfined medium responds to multiple high-energy partons depositing energy and momentum, revealing interactions of their wakes relevant for understanding collective flow in high-energy nuclear collisions.

Contribution

It introduces a detailed analysis of the medium's response to multiple moving partons and their wake interactions, advancing understanding of collective effects in heavy-ion collisions.

Findings

Wakes from multiple partons interact within the medium.

Energy and flow profiles depend on parton trajectories.

Implications for collective expansion in LHC collisions.

Abstract

We investigate the response of non-expanding deconfined hot matter to energy and momentum deposition from a pair of partons moving with high energies. Several situations are examined with partons moving so that the generated wakes in the medium interact. The resulting energy and flow profiles are studied. Such cases are relevant for nuclear collisions at the LHC where several hard partons are produced in a single collision and their contribution to collective expansion of the fireball may be important.
