Jet hadrochemistry as a characteristics of jet quenching

TL;DR

This paper explores how jet quenching in heavy-ion collisions at the LHC affects the hadrochemical composition of jet fragments, revealing potential signatures of medium interactions in jet chemistry.

Contribution

It introduces the concept that jet hadrochemistry can serve as a new observable for studying medium effects in jet quenching phenomena.

Findings

Medium-modification of parton showers alters jet hadrochemistry.

Jet hadrochemistry signatures can be observed without medium effects at hadronization.

Study provides a framework for analyzing jet chemistry in high-multiplicity environments.

Abstract

Jets produced in nucleus-nucleus collisions at the LHC are expected to be strongly modified due to the interaction of the parton shower with the dense QCD matter. Here, we point out that jet quenching can leave signatures not only in the longitudinal and transverse jet energy and multiplicity distributions, but also in the hadrochemical composition of the jet fragments. In particular, we show that even in the absence of medium effects at or after hadronization, the medium-modification of the parton shower can result in significant changes in jet hadrochemistry. We discuss how jet hadrochemistry can be studied within the high-multiplicity environment of nucleus-nucleus collisions at the LHC.
