A simultaneous understanding of jet and hadron suppression

TL;DR

This paper presents a comprehensive analysis of jet and hadron suppression using a hybrid model, successfully fitting data from RHIC and LHC and elucidating the underlying mechanisms of energy loss and jet structure.

Contribution

It introduces a hybrid strong/weak coupling model that accurately describes jet and hadron suppression, highlighting the importance of jet width and plasma resolution effects.

Findings

Wider jets lose more energy than narrower jets.

The model fits RHIC and LHC data successfully.

Jet fragmentation functions reveal the suppression mechanisms.

Abstract

In the context of the hybrid strong/weak coupling model for jet quenching, we perform a global fit to hadron and jet data in the most central bins both at RHIC and LHC. The qualitative and quantitative success of the analysis is attributed to the fact that the model correctly captures the fact that wider jets lose, on average, more energy than the narrower ones, to which high energy hadrons belong. We show how one can understand the relative jet and hadron suppression by analyzing the jet fragmentation functions, and also discuss the role of plasma finite resolution effects.
