Matching the non-equilibrium initial stage of heavy ion collisions to hydrodynamics with QCD kinetic theory / Kurkela, Aleksi (CERN ; Stavanger U.) ; Mazeliauskas, Aleksas (U. Heidelberg, ITP) ; Paquet, Jean-Francois (Duke U.) ; Schlichting, Sören (Bielefeld U.) ; Teaney, Derek (SUNY, Stony Brook)
In the collision of nuclei at high energies the produced matter reinteracts and forms a plasma which ultimately equilibrates and exhibits collective hydrodynamic flow. While a general theory of the equilibration process has been outlined previously, there were no practical frameworks to smoothly connect the early gluon production in classical field simulations with hydrodynamic simulations of the late time plasma expansion.

Hydrodynamic attractors, initial state energy and particle production in relativistic nuclear collisions / Giacalone, Giuliano (IPhT, Saclay) ; Mazeliauskas, Aleksas (Heidelberg U. ; CERN) ; Schlichting, Sören (Bielefeld U.)
We exploit the concept of hydrodynamic attractors to establish a general relation between the initial state energy and the produced particle multiplicities in high-energy nuclear collisions. When combined with an ab initio model of energy deposition, the entropy production during the pre-equilibrium phase naturally explains the universal centrality dependence of the measured charged particle yields in nucleus-nucleus collisions.

2+1D simulations of pre-equilibrium stage with QCD kinetic theory / Kurkela, Aleksi (CERN ; Stavanger U.) ; Mazeliauskas, Aleksas (Heidelberg U.) ; Paquet, Jean-François (Duke U.) ; Schlichting, Sören (Bielefeld U.) ; Teaney, Derek (Stony Brook U.)
The produced matter in the high energy nuclear collisions reinteracts and forms a plasma which ultimately equilibrates and exhibits collective hydrodynamic flow. The connection between the early gluon production in classical field simulations and hydrodynamic expansion at later times is given by the QCD kinetic theory. [...]

Matching the non-equilibrium initial stage of heavy ion collisions to hydrodynamics with QCD kinetic theory / Kurkela, Aleksi (CERN ; Stavanger U.) ; Mazeliauskas, Aleksas (U. Heidelberg, ITP ; Stony Brook U.) ; Paquet, Jean-François (Duke U. ; Stony Brook U.) ; Schlichting, Sören (Washington U., Seattle) ; Teaney, Derek (Stony Brook U.)
High-energy nuclear collisions produce a nonequilibrium plasma of quarks and gluons which thermalizes and exhibits hydrodynamic flow. There are currently no practical frameworks to connect the early particle production in classical field simulations to the subsequent hydrodynamic evolution. [...]

Effective kinetic description of event-by-event pre-equilibrium dynamics in high-energy heavy-ion collisions / Kurkela, Aleksi (CERN ; Stavanger U.) ; Mazeliauskas, Aleksas (Heidelberg U. ; Stony Brook U.) ; Paquet, Jean-François (Duke U. ; Stony Brook U.) ; Schlichting, Sören (Washington U., Seattle) ; Teaney, Derek (Stony Brook U.)
We develop a macroscopic description of the space-time evolution of the energy-momentum tensor during the pre-equilibrium stage of a high-energy heavy-ion collision. Based on a weak coupling effective kinetic description of the microscopic equilibration process (\`a la "bottom-up"), we calculate the non-equilibrium evolution of the local background energy-momentum tensor as well as the non-equilibrium linear response to transverse energy and momentum perturbations for realistic boost-invariant initial conditions for heavy ion collisions.

Predictions for cold nuclear matter effects on charged hadrons, identified light hadrons, quarkonium and heavy flavor hadrons, Drell-Yan dileptons, jets, photons, gauge bosons and top quarks produced in $p+$Pb collisions at $\sqrt{s_{_{NN}}} = 8.16$ TeV are compiled and, where possible, compared to each other. Predictions of the normalized ratios of $p+$Pb to $p+p$ cross sections are also presented for most of the observables, providing new insights into the expected role of cold nuclear matter effects.

Initial conditions for hydrodynamics from kinetic theory equilibration / Kurkela, Aleksi (CERN ; Stavanger U.) ; Mazeliauskas, Aleksas (SUNY, Stony Brook ; U. Heidelberg, ITP) ; Paquet, Jean-François (SUNY, Stony Brook) ; Schlichting, Sören (Washington U., Seattle) ; Teaney, Derek (SUNY, Stony Brook)
We use effective kinetic theory to study the pre-equilibrium dynamics in heavy-ion collisions. We describe the evolution of linearized energy perturbations on top of out-of-equilibrium background to the energy-momentum tensor at a time when hydrodynamics becomes applicable. [...]
