Tagged jets and jet reconstruction as a probe of the quark-gluon plasma

TL;DR

This paper discusses how tagged jets, especially Z boson-associated jets, can be used to probe the quark-gluon plasma in heavy-ion collisions, providing insights into parton energy loss mechanisms.

Contribution

It presents new results on Z boson-tagged jet production and suppression in heavy-ion collisions using the GLV energy loss model, advancing understanding of jet quenching.

Findings

High-energy Z-tagged jets are suppressed in heavy-ion collisions.

Results support the role of radiative energy loss in jet quenching.

Data helps distinguish between different QGP interaction models.

Abstract

The large center-of-mass energies available to the heavy-ion program at the LHC and recent experimental advances at RHIC will enable QCD matter at very high temperatures and energy densities, that is, the quark-gluon plasma (QGP), to be probed in unprecedented ways. Fully-reconstructed inclusive jets and the away-side hadron showers associated with electroweak bosons, that is, tagged jets, are among these exciting new probes. 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 these exciting new fields of research can help resolve some of the most controversial points in heavy ion physics today such as the significance of the radiative, collisional and dissociative processes in the QGP and the applicability of strong versus weak coupling regimes to describe jet production and propagation. In this proceedings, I will 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.
