Elastic energy loss with respect to the reaction plane in a Monte-Carlo model

TL;DR

This paper models elastic energy loss of hard partons in heavy-ion collisions to compare with experimental data, revealing that incoherent elastic energy loss cannot explain observed phenomena.

Contribution

It introduces a Monte-Carlo simulation of elastic energy loss in a hydrodynamical medium and assesses its compatibility with experimental measurements.

Findings

Incoherent elastic energy loss does not match experimental data.

Monte-Carlo model provides detailed energy loss predictions.

Elastic energy loss alone is insufficient to explain nuclear modification factors.

Abstract

We present a computation of $\pi^0$ nuclear modification factor with respect to the reaction plane in Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV, based on a Monte-Carlo model of elastic energy loss of hard partons traversing the bulk hydrodynamical medium created in ultrarelativistic heavy-ion collisions. We find the incoherent nature of elastic energy loss incompatible with the measured data.
