78. Studying the QCD phase diagram through higher-order fluctuations in RHIC-BES at STAR

Dr Toshihiro Nonaka (University of Tsukuba)

Talk

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...

73. Light-nuclei production in heavy-ion collisions in Three-fluid Hydrodynamics-based Event Simulator (THESEUS)

Marina Kozhevnikova (Joint Institute for Nuclear Research, Dubna, Russia)

31/08/2021, 11:30

Talk

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...

251. Vorticity in Heavy-Ion Collisions at NICA Energies

Dr Evgeny Kolomeitsev (LTP JINR, Dubna)

31/08/2021, 12:00

Talk

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...

13. A machine learning procedure for the selection of muon track candidates in the CBM experiment.

Anna Senger (GSI)

31/08/2021, 12:30

Talk

The mission of the Compressed Baryonic Matter (CBM) experiment at the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt is to explore the QCD phase diagram at high net baryon densities likely to exist in the core of neutron stars. The CBM detector system is designed to perform multi-differential measurements of hadrons and leptons in central gold-gold collisions at beam...

175. Ambiguities in the hadro-chemical freeze-out of Au+Au collisions at SIS18 energies and how to resolve them

Anton Motornenko (Frankfurt Institute for Advanced Studies)

31/08/2021, 13:00

Talk

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...

35. Feasibility studies of strangeness production in heavy-ion interactions at the BM@N experiment

Alexandre Zinchenko (Joint Institute for Nuclear Research (RU))

31/08/2021, 17:00

Talk

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. ...

43. The Compressed Baryonic Matter (CBM) Experiment at FAIR

Kshitij Agarwal (Eberhard Karls Universität Tübingen)

31/08/2021, 17:30

Talk

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...

294. Asymmetry energy and nuclear matter equation of state: High density perspectives at GSI/FAIR.

Dr Arnaud LeFevre (GSI)

31/08/2021, 18:00

Talk

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...

25. The heavy-ion program of the BM@N Experiment at NICA

Prof. Peter Senger (FAIR)

31/08/2021, 18:30

Talk

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...
