Simulating collectivity in dense baryon matter with multiple fluids

Abstract

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-Au collisions in the RHIC Beam Energy Scan program. We also show the $p_T$-differential and $p_T$-integrated polarization of (anti-)$\hat{I}›$ hyperons. In MUFFIN simulations, we observe a strong splitting between polarizations of $\hat{I}›$ and anti-$\hat{I}›$. The splitting is driven purely by a finite baryon chemical potential.
