abstract

A set of different equations of state is implemented in the molecular dynamics part of a non-equilibrium transport simulation (UrQMD) of heavy-ion collisions. It is shown how different flow observables are affected by the density dependence of the equation of state. In particular, the effects of a phase transition at high density are explored, including an expected reduction in mean $m_T$. We also show that an increase in $v_2$ is characteristic for a strong softening of the equation of state. The phase transitions with a low coexistence density, $n_{\mathrm{CE}}<4 n_0$, show a distinct minimum in the slope of the directed flow as a function of the beam energy, which would be a clear experimental signal. By comparing our results with experimental data, we can exclude any strong phase transition at densities below $4n_0$.

  1. Poincar\'e covariant quantum molecular dynamics: a covariant description of a system of interacting wave packets

    hep-ph 2025-07 conditional novelty 7.0 of 10

    The authors derive Poincaré-covariant mean-field equations of motion for relativistic QMD and show they match Monte-Carlo integration of the exact forces in heavy-ion collisions.

  2. Untangling the interplay of the Equation-of-State and the Collision Term towards the generation of Directed and Elliptic Flow at intermediate energies

    nucl-th 2024-11 conditional novelty 7.0 of 10

    In UrQMD simulations of Au+Au at SIS18/SIS100 energies, the final midrapidity elliptic flow is generated late by the mean-field potential during the breakup of a matter bridge, not by early squeeze-out or spectator shadowing.

  3. Space-time regions of high baryon density and baryon stopping in heavy-ion collisions

    nucl-th 2026-02 conditional novelty 6.0 of 10

    3FD hydrodynamics predicts larger and longer-lived regions of dense baryon matter in Au+Au collisions at 3–19.6 GeV than JAM transport, with V4(3n0) decreasing monotonically with energy.

  4. Building Neutron Stars with the MUSES Calculation Engine

    nucl-th 2025-02 conditional novelty 6.0 of 10

    A new open-source calculation engine produces crust-to-core neutron star equations of state and shows that smooth matching choices change predicted radii and masses by several percent.

  5. Simultaneous description of high density QCD matter in heavy ion collisions and neutron star observations

    hep-ph 2025-01 conditional novelty 6.0 of 10

    An equation of state selected to match neutron star mass-radius data also describes HADES heavy-ion observables when implemented with momentum-dependent potentials in UrQMD.
