TL;DR: In this paper, a hybrid transport model was developed to combine the strengths of both of these approaches: heavy quarks scatter with medium partons using matrix-elements calculated in perturbative QCD, while between these discrete hard scatterings they evolve using a Langevin equation with empirical transport coefficients to capture the nonperturbative soft part of the interaction.

TL;DR: In this article, the authors investigated the elliptic and triangular flow of heavy mesons in ultrarelativistic heavy-ion collisions at the BNL Relatiistic Heavy-Ion Collider and the CERN Large Hadron Collider (LHC).

TL;DR: The Gaussian radius parameters of the pion-emitting source in high-energy heavy-ion collisions, assuming a first-order phase transition from a thermalized quark-gluon plasma (QGP) to a gas of hadrons, are calculated.

TL;DR: In this paper, a Bayesian model-to-data analysis was applied to estimate the temperature and momentum dependence of the heavy quark diffusion coefficient in an improved Langevin framework, and the posterior range of the diffusion coefficient was obtained by performing a Markov chain Monte Carlo random walk and calibrating on the experimental data of $D$-meson.

TL;DR: In this article, the assumption of local equilibrium in relativistic heavy ion collisions at energies from 10.7 AGeV up to 160AGeV was checked in the microscopic transport model.
