Importance of the Bulk Viscosity of QCD in Ultrarelativistic Heavy-Ion Collisions.

TL;DR: This work investigates the consequences of a nonzero bulk viscosity coefficient on the transverse momentum spectra, azimuthal momentum anisotropy, and multiplicity of charged hadrons produced in heavy ion collisions at LHC energies.

Heavy Ion Collisions: The Big Picture, and the Big Questions

TL;DR: The physics of heavy ion collisions quickly form a droplet of quark-gluon plasma (QGP) with a remarkably small viscosity as discussed by the authors, which is perhaps the simplest form of complex quantum matter that we know of.

Relativistic Fluid Dynamics In and Out of Equilibrium -- Ten Years of Progress in Theory and Numerical Simulations of Nuclear Collisions

TL;DR: The relativistic viscous fluid dynamics was formulated from first principles in an effective field theory framework, based entirely on the knowledge of symmetries and long-lived degrees of freedom.

Observation of Long-Range Elliptic Azimuthal Anisotropies in s =13 and 2.76 TeV pp Collisions with the ATLAS Detector

Georges Aad, +2854 more
TL;DR: The results suggest that the ridge in pp collisions arises from the same or similar underlying physics as observed in p+Pb collisions, and that the dynamics responsible for the ridge has no strong sqrt[s] dependence.

A Multidimensional unfolding method based on Bayes' theorem

TL;DR: In this paper, the authors proposed an iterative method to unfold experimental distributions in order to get the best estimates of the true ones, where the weak point of the Bayes approach, namely the need of the knowledge of the initial distribution, can be overcome by an iteration procedure.

Methods for analyzing anisotropic flow in relativistic nuclear collisions

TL;DR: In this article, the Fourier expansion of azimuthal distributions is used to analyze anisotropic flow (directed, elliptic, etc.) in relativistic nuclear collisions, and formulas relevant for this approach are presented.
