Sub-jet structure as a discriminating quenching probe

TL;DR

This paper introduces jet substructure observables that are less affected by hadronization uncertainties, enabling better discrimination between different jet quenching models in high-energy physics.

Contribution

It proposes a new class of jet substructure observables that improve the discrimination of jet quenching models, with reduced sensitivity to hadronization effects.

Findings

Sub-jet structures effectively distinguish between jet quenching models.

The new observables are largely insensitive to hadronization physics.

Enhanced discriminating power compared to traditional methods.

Abstract

In this work, we propose a new class of jet substructure observables which, unlike fragmentation functions, are largely insensitive to the poorly known physics of hadronization. We show that sub-jet structures provide us with a large discriminating power between different jet quenching Monte Carlo implementations.
