TL;DR: Using combined data from the Relativistic Heavy Ion and Large Hadron Colliders, Bayesian model averaging is propagate an estimate of the model uncertainty generated by the transition from hydrodynamics to hadron transport in the plasma's final evolution stage, providing the most reliable phenomenological constraints to date on the QGP viscosities.

TL;DR: In this paper, the modification of hard jets in an extended static medium held at a fixed temperature is studied using three different Monte Carlo event generators: linear Boltzmann transport (LBT), modular all twist transverse-scattering elastic-drag and radiation (MATTER), and modular algorithm for relativistic treatment of heavy-ion interactions (MARTINI).

TL;DR: This article outline the algorithmic design of the JETSCAPE framework, define the interfaces and describe the default modules required to carry out full simulations of heavy-ion collisions within this package, and describes the physics output for both $p$-$p$ and $A$-$A$ collisions from the default distribution.

TL;DR: The JETSCAPE framework is a modular and versatile Monte Carlo software package for the simulation of high energy nuclear collisions as mentioned in this paper, which can be used to simulate A+A collisions with a wide range of collision energies at a level comparable to standard Monte Carlo codes.

Energy and scale dependence of q ̂ and the “JET puzzle”
TL;DR: In this article, the authors present an attempt to probe the underlying structure of the quark-gluon plasma (QGP) at high resolution, based on the extracted jet transport coefficient $\stackrel{\ifmmode \hat{}\else \^{}\fi{}}{q}$.
