Understanding QCD phase structure is one of ultimate goals of high-energy heavy-ion colliding experiments.
At BNL-RHIC, the Beam Energy Scan (BES-I) program was carried out from 2010 to 2017.
Data sets of Au+Au collisions were collected for various collision energies
from $\sqrt{s_{\rm NN}}=200$ GeV down to $7.7$ GeV by the STAR experiment.
Recently, the STAR collaboration reported a...
In this talk we present an updated version of event generator THESEUS, based on the three-fluid dynamics (3FD), supplemented by UrQMD cascade for the late stage of the nuclear collision.
The generator gives opportunity to simulate light-nuclei production in relativistic heavy-ion collisions via thermal mechanism, on the same basis as hadrons. The generator is designed for BES-RHIC, SPS, NICA...
Within the transport model PHSD we analyze properties of the medium created at different stages of heavy-ions collision at NICA energies.
Nucleons of colliding nuclei are separated in participants and spectators, and the transition initial angular momentum to the fireball of participants is investigated.
Criteria for the selection of events with the highest internal angular momentum for...
The thermal fit to preliminary HADES data of Au+Au collisions at $\sqrt{s_{_{NN}}}=2.4$ GeV shows two degenerate solutions at $T\approx50$ MeV and $T\approx70$ MeV. The analysis of the same particle yields in a transport simulation of the UrQMD model yields the same features, i.e. two distinct temperatures for the chemical freeze-out. While both solutions yield the same number of hadrons after...
In fall 2021, the accelerator complex of the Booster and Nuclotron at the Nuclotron Based Ion Collider Facility (NICA) at JINR (Dubna) will be ready to accelerate heavy ions. At the same time, the Baryonic Matter at Nuclotron (BM@N) experimental setup is completing its configuration to investigate relativistic heavy-ion beam interactions with fixed targets. ...
The Compressed Baryonic Matter (CBM) experiment is one of the major scientific pillars of the future Facility for Antiproton and Ion Research (FAIR), which presently is under construction adjacent to the GSI Helmholtz Centre in Darmstadt, Germany, and is expected to come under operation in 2025. The goal of the CBM at FAIR is to explore the QCD phase diagram in the region of high baryon...
From several heavy-ion collision (HIC) experiments at relativistic energies (ALADiN, KaoS, FOPI, ASY-EOS) performed with the SIS accelerator at GSI Darmstadt in the last three decades, a density dependence of the nuclear equation of states can be drawn from 0.3 to 2 times the saturation density, for both the symmetric matter (KaoS, FOPI experiments) and the symmetry energy part of the nuclear...
The QCD phase diagram in the region of large baryon-chemical potentials is increasingly attracting interest within the nuclear and astrophysics community. Heavy-ion collision experiments in the laboratory and astronomical observations complement each other, in order to explore the equation-of-state and the elementary degrees-of-freedom of high-density matter. Presently, the Baryonic...
