We present results for fluctuations of the baryon number for QCD at non-zero temperature and chemical potential. These are extracted from solutions to a coupled set of truncated Dyson-Schwinger equations for the quark and gluon propagators of Landau gauge QCD with N f = 2 + 1 quark flavors, that has been studied previously. We discuss the changes of fluctuations and ratios thereof up to fourth order for several temperatures and baryon chemical potential up to and beyond the critical end point. In the context of preliminary STAR data for the skewness and kurtosis ratios, the results are compatible with the scenario of a critical end point at large chemical potential and slightly offset from the freeze-out line. We also discuss the caveats involved in this comparison.

“…The particle yields at midrapidity from PHSD are connected by lines (to draw the eye) although experimental data (taken from Refs. [19,[48][49][50][51][52][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68]) and calculations do not always correspond to the same centrality selection (and system) for different bombarding energies. However, for given √ s NN , the data and calculation correspond to the same centrality and collision system.…”

The dynamics of baryon-antibaryon annihilation and reproduction (BB ↔ 3M) is studied within the PartonHadron-String Dynamics (PHSD) transport approach for Pb+Pb and Au+Au collisions as a function of centrality from lower Super Proton Synchrotron (SPS) up to Large Hadron Collider (LHC) energies on the basis of the quark rearrangement model. At Relativistic Heavy-Ion Collider (RHIC) energies we find a small net reduction of baryon-antibaryon (BB) (2013)], where a deviation of 2.7 σ was claimed by the ALICE Collaboration, should not be attributed to a net antiproton annihilation. This is in line with the observation that no substantial deviation between the data and statistical hadronization model (SHM) calculations is seen for antihyperons, since according to the PHSD analysis the antihyperons should be modified by the same amount as antiprotons. As the PHSD results for particle ratios are in line with the ALICE data (within error bars) this might point towards a deviation from statistical equilibrium in the hadronization (at least for protons and antiprotons). Furthermore, we find that the BB ↔ 3M reactions are more effective at lower SPS energies where a net suppression for antiprotons and antihyperons up to a factor of 2-2.5 can be extracted from the PHSD calculations for central Au+Au collisions.

“…Many authors have tried to analyze the chemical freeze-out conditions. Those include the results fluctuations analysis from Lattice QCD [18][19][20][21][22], HRG model [12] and other methods [23,24]. In the low baryon density region, µ B ≤ 400 MeV, the µ B dependence of the freeze-out temperature is quite weak and the value of the freeze-out temperature is around [150][151][152][153][154][155][156][157][158][159][160] MeV.…”

With the aim of understanding the phase structure of nuclear matter created in high-energy nuclear collisions at finite baryon density, a beam energy scan program has been carried out at Relativistic Heavy Ion Collider (RHIC). In this mini-review, most recent experimental results on collectivity, criticality and heavy flavor productions will be discussed. The goal here is to establish the connection between current available data and future heavy-ion collision experiments in a high baryon density region.Particles 2020, xx, 5 0 -5% 60 -80% 0 -5% Au+Au at RHIC Pb+Pb at LHC A.
