The ALICE experiment was proposed in 1993, to study strongly-interacting matter at extreme
energy densities and temperatures. This proposal entailed a comprehensive investigation of …

Although seemingly disparate, high-energy nuclear physics (HENP) and machine learning
(ML) have begun to merge in the last few years, yielding interesting results. It is worthy to …

This manual describes the Pythia event generator, the most recent version of an evolving
physics tool used to answer fundamental questions in particle physics. The program is most …

We report a new determination of q ̂, the jet transport coefficient of the quark-gluon plasma.
We use the JETSCAPE framework, which incorporates a novel multistage theoretical …

We present a new study of jet interactions in the quark-gluon plasma created in high-energy
heavy-ion collisions, using a multistage event generator within the jetscape framework. We …

Jet quenching has been used successfully as a hard probe to study properties of the quark–
gluon plasma (QGP) in high-energy heavy-ion collisions at both the relativistic heavy-ion …

Heavy ion collisions quickly form a droplet of quark–gluon plasma (QGP) with a remarkably
small viscosity. We give an accessible introduction to how to study this smallest and hottest …

Hot QCD physics studies the nuclear strong force under extreme temperature and densities.
Experimentally these conditions are achieved via high-energy collisions of heavy ions at the …

Studies of fluctuations and correlations of soft hadrons and hard and electromagnetic probes
of the dense and strongly interacting medium require event-by-event hydrodynamic …

Studies of fully-reconstructed jets in heavy-ion collisions aim at extracting thermodynamical
and transport properties of hot and dense QCD matter. Recently, a plethora of new jet …
