The first measurements of anisotropic flow coefficients for vn mid-rapidity charged particles in Xe–Xe collisions at √sNN=5.44 TeV are presented. Comparing these measurements to those from Pb–Pb collisions at √sNN=5.02 TeV, v2 is found to be suppressed for mid-central collisions at the same centrality, and enhanced for central collisions. The values of v3 are generally larger in Xe–Xe than in Pb–Pb at a given centrality. These observations are consistent with expectations from hydrodynamic predictions. When both and are divided by their corresponding eccentricities for a variety of initial state models, they generally scale with transverse density when comparing Xe–Xe and Pb–Pb, with some deviations observed in central Xe–Xe and Pb–Pb collisions. These results assist in placing strong constraints on both the initial state geometry and medium response for relativistic heavy-ion collisions.

Diffusion processes involving multiple conserved charges : a study from kinetic theory and implications to the fluid-dynamical modeling of heavy ion collisions
Fotakis, Jan A.; Greif, Moritz; Greiner, Carsten; Denicol, Gabriel S.; Niemi, Harri (American Physical Society, 2020)The bulk nuclear matter produced in heavy ion collisions carries a multitude of conserved quantum numbers: electric charge, baryon number, and strangeness. Therefore, the diffusion processes associated with these conserved ... -
