Bayesian uncertainty quantification of perturbative QCD input to the neutron-star equation of state
Gorda, Tyler; Komoltsev, Oleg; Kurkela, Eero Aleksi; Mazeliauskas, Aleksas (Peer reviewed; Journal article, 2023)The equation of state of neutron-star cores can be constrained by requiring a consistent connection to the perturbative Quantum Chromodynamics (QCD) calculations at high densities. The constraining power of the QCD input ... -
Chemical equilibration in hadronic collisions
Kurkela, Aleksi; Mazeliauskas, Aleksas (Peer reviewed; Journal article, 2019)We study chemical equilibration in out-of-equilibrium quark-gluon plasma using the first principles method of QCD effective kinetic theory, accurate at weak coupling. In longitudinally expanding systems—relevant for ... -
Chemical equilibration in weakly coupled QCD
Kurkela, Aleksi; Mazeliauskas, Aleksas (Peer reviewed; Journal article, 2019)We study thermalization, hydrodynamization, and chemical equilibration in out-of-equilibrium quark-gluon plasma starting from various initial conditions using QCD effective kinetic theory, valid at weak coupling. In ... -
Collective flow in single-hit QCD kinetic theory
Kurkela, Eero Aleksi; Mazeliauskas, Aleksas; Törnkvist, Robin (Peer reviewed; Journal article, 2021-11)Motivated by recent interest in collectivity in small systems, we calculate the harmonic flow response to initial geometry deformations within weakly coupled QCD kinetic theory using the first correction to the free-streaming ... -
Discovering Partonic Rescattering in Light Nucleus Collisions
Huss, Alexander; Kurkela, Eero Aleksi; Mazeliauskas, Aleksas; Paatelainen, Risto; van der Schee, Wilke; Wiedemann, Urs Achim (Peer reviewed; Journal article, 2021-05)We demonstrate that oxygen-oxygen collisions at the LHC provide unprecedented sensitivity to parton energy loss in a system whose size is comparable to those created in very peripheral heavy-ion collisions. With leading ... -
Effective kinetic description of event-by-event pre-equilibrium dynamics in high-energy heavy-ion collisions
Kurkela, Aleksi; Mazeliauskas, Aleksas; Paquet, Jean-Francois; Schlichting, Sören; Teaney, Derek (Peer reviewed; Journal article, 2019)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 ... -
Matching the Nonequilibrium Initial Stage of Heavy Ion Collisions to Hydrodynamics with QCD Kinetic Theory
Kurkela, Aleksi; Mazeliauskas, Aleksas; Paquet, Jean-Francois; Schlichting, Sören; Teaney, Derek (Peer reviewed; Journal article, 2019-03)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 ... -
Predicting parton energy loss in small collision systems
Huss, Alexander; Kurkela, Aleksi; Mazeliauskas, Aleksas; Paatelainen, Risto; van der Schee, Wilke; Wiedemann, Urs Achim (Peer reviewed; Journal article, 2021)Medium induced parton energy loss is not conclusively established either in very peripheral heavy-ion collisions or in proton-ion collisions. However, the standard interpretation of azimuthal momentum anisotropies in these ...
