Friction terms in multi-fluid description of heavy-ion collisions
Clemens Werthmann, Iurii Karpenko, Pasi Huovinen
In multi-fluid description of heavy-ion collisions, the primary scatterings and particle production are described in terms of interaction between fluids, so called friction. These…
Extended applicability domain of viscous anisotropic hydrodynamics in (2+1)-D Bjorken flow with transverse expansion
Yiyang Peng, Victor E. Ambrus, Clemens Werthmann +3
We perform (2+1)-D simulations of viscous anisotropic hydrodynamics (VAH) under boost-invariant and conformal conditions. Comparing both VAH and traditional viscous hydrodynamics w…
Quantifying the degree of hydrodynamic behaviour in heavy-ion collisions
Sören Schlichting, Clemens Werthmann
Exploiting the first measurements of the same ion species in O+O collisons at RHIC and LHC, we propose an experimentally accessible observable to distinguish whether collective beh…
Simulating collectivity in dense baryon matter with multiple fluids
Iurii Karpenko, Jakub Cimerman, Pasi Huovinen +1
We report on construction of a modern multi-fluid approach to heavy-ion collisions at FAIR/BES energies (MUFFIN) and show the reproduction of basic experimental observables in Au-A…
Collective dynamics in heavy and light-ion collisions -- II) Determining the origin of collective behavior in high-energy collisions
Victor E. Ambrus, Sören Schlichting, Clemens Werthmann
Exploiting the first measurements of the same ion species in OO collisons at RHIC and LHC, we propose an observable to distinguish whether collective behavior builds up through a h…
Collective dynamics in heavy and light-ion collisions -- I) Kinetic Theory vs. Hydrodynamics
Victor E. Ambrus, Sören Schlichting, Clemens Werthmann
High-energy nuclear collisions exhibit collective flow, which emerges as a dynamical response of the Quark-Gluon Plasma (QGP) to the initial state geometry of the collision. Collec…
