Tagged jets and jet reconstruction as a probe of QGP induced partonic energy loss

TL;DR

This paper discusses how tagged jets and full jet reconstruction techniques at RHIC and LHC can probe the quark-gluon plasma by revealing partonic energy loss mechanisms, with results supporting the GLV energy loss model.

Contribution

It introduces the use of tagged jets as a novel probe for studying partonic energy loss in QGP, providing new insights into jet suppression phenomena.

Findings

High energy jets tagged with Z bosons show suppression consistent with energy loss models.

Jet spectra and suppression patterns support the applicability of the GLV formalism.

Results help clarify the mechanisms of partonic energy loss in QGP.

Abstract

Recent experimental advances at the Relativistic Heavy Ion Collider (RHIC) and the large center-of-mass energies available to the heavy-ion program at the Large Hadron Collider (LHC) will enable strongly interacting matter at high temperatures and densities, that is, the quark-gluon plasma (QGP), to be probed in unprecedented ways. Among these exciting new probes are fully-reconstructed inclusive jets and the away-side hadron showers associated with a weakly or electromagnetically interacting boson, or, tagged jets. Full jet reconstruction provides an experimental window into the mechanisms of quark and gluon dynamics in the QGP which is not accessible via leading particles and leading particle correlations. Theoretical advances in this growing field can help resolve some of the most controversial points in heavy ion physics today. I here discuss the power of jets to reveal the spectrum of induced radiation, thereby shedding light on the applicability of the commonly used energy loss formalisms and present results on the production and subsequent suppression of high energy jets tagged with Z bosons in relativistic heavy-ion collisions at RHIC and LHC energies using the Gyulassy-Levai-Vitev (GLV) parton energy loss approach.
