Spectator shadowing as the source of the breaking of NCQ scaling at RHIC-FXT and FAIR energies
Tom Reichert, Iurii Karpenko
The apparent scaling of the elliptic flow of identified hadrons with the number of constituent quarks indicates the presence of quark coalescence, and in turn suggests the presence…
Unshadowing the constituent quark number scaling of harmonic flow in heavy-ion collisions
Tom Reichert, Iurii Karpenko
Constituent quark number scaling of elliptic flow has been proposed as one key observable to identify the phase transition or the absence of the Quark-Gluon Plasma (QGP) in heavy-i…
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…
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…
Directed flow and hyperon polarization at RHIC BES from multi-fluid dynamics
Iurii Karpenko, Jakub Cimerman
We present directed flow of protons and pions, as well as mean polarization of and hyperons computed for Au-Au collisions at GeV in MUFF…
Simulating collectivity in dense baryon matter with multiple fluids
Jakub Cimerman, Iurii Karpenko, Boris Tomasik +1
A novel three-fluid dynamical model for simulations of heavy-ion collisions at RHIC Beam Energy Scan programme, called MUFFIN, has been developed. The novelty consists of modular i…
