Modeling the jet quenching in hot and dense QCD matter

TL;DR

This paper discusses modeling jet quenching in hot QCD matter, emphasizing its role as a probe of quark-gluon plasma and integrating it into Monte Carlo simulations to interpret RHIC and LHC data.

Contribution

It introduces the inclusion of jet quenching effects into the HYDJET++ Monte Carlo model for heavy ion collisions.

Findings

Jet quenching effects significantly influence particle spectra.

The HYDJET++ model can reproduce key experimental observables.

Collective flow effects are incorporated alongside jet quenching.

Abstract

One of the important perturbative ("hard") probes of hot and dense QCD matter is the medium-induced energy loss of energetic partons, so called "jet quenching", which is predicted to be very different in cold nuclear matter and in QGP, and leads to a number of phenomena which are already seen in the RHIC data on the qualitative level. The inclusion of jet quenching and other important collective effects, such as radial and elliptic flows, in the existing Monte-Carlo models of relativistic heavy ion collisions is discussed. Some issues on the corresponding physical observables at RHIC and LHC energies obtained with HYDJET++ model are presented.
