Collective flow in single-hit QCD kinetic theory

Kurkela, Aleksi ; Mazeliauskas, Aleksas and Törnkvist, Robin LU (2021) In Journal of High Energy Physics 2021(11).
Abstract

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 background. We derive a parametric scaling formula that relates harmonic flow in systems of different sizes and different generic initial gluon distributions. We comment on similarities and differences between the full QCD effective kinetic theory and the toy models used previously. Finally we calculate the centrality dependence of the integrated elliptic flow v2 in oxygen-oxygen, proton-lead and proton-proton collision systems.
