Hadron polarization and equation of state at FAIR/RHIC-BES energies
Dai-Neng Liu, Jan Steinheimer, Kai-Jia Sun +3
The global polarization indicates that hot and dense matter created in non-central heavy-ion collisions carries large orbital angular momentum. However, the relation between h…
Transport simulations with a constrained momentum-dependent Chiral Mean Field EoS at different iso-spin fractions
Jan Steinheimer, Marcus Bleicher
We present a comparison of the UrQMD model using a chiral mean field EoS (CMF) with flow and pion production data in heavy ion collisions at low beam energies $E_{\mathrm{lab}}=0.2…
Non-monotonicity of correlations from meson-baryon mixing
Tom Reichert, Jan Steinheimer, Marcus Bleicher
The STAR experiment has recently reported data on the charged hadron correlation in Au+Au reactions from…
Hypernucleus production in p+Au reactions at the FAIR facility
Nitikorn Jaingarm, Pornrad Srisawad, Christoph Herold +3
We explore the production of hypernuclei in p+Au reactions using the UrQMD model accompanied by a standard phase space coalescence model. We focus on the proton beam energy range o…
Resonance Suppression in Ar+Sc Collisions at SPS Energies
Amine Chabane, Tom Reichert, Jan Steinheimer +1
We investigate the production and suppression of short-lived resonances in p+p and Ar+Sc collisions at CERN-SPS energies ( 8.8, 11.9, and 16.8…
Enhanced Neutrino Cooling from Parity-Doubled Nucleons in Neutron Star Cooling Simulations
Rodrigo Negreiros, Liam Brodie, Jan Steinheimer +2
Although restoration of chiral symmetry is predicted by quantum chromodynamics to take place at high baryon density, most modeling of neutron star interiors disregards a chiral pha…
