“…Figure 7 shows the rapidity density of baryons and antibaryons from PHSD at midrapidity in comparison to data from the PHENIX and STAR Collaborations [48,54,55] experimental data are slightly overestimated (except for + 0 ), while calculations with only BB annihilation (dashed red lines) show a slight tendency to underestimate the data. The results from PHSD calculations with the 2 ↔ 3 reactions included are displayed by the black solid lines and lie in between the other limits.…”

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.

ΛΛinteraction from relativistic heavy-ion collisions

We investigate the two-particle intensity correlation function of in relativistic heavy-ion collisions. We find that the behavior of the correlation function at small relative momenta is fairly sensitive to the interaction potential and collective flows. By comparing the results of different source functions and potentials, we explore the effect of intrinsic collective motions on the correlation function. We find that the recent STAR data give a strong constraint on the scattering length and effective range of interaction, as −1.8 fm −1 < 1/a 0 < −0.8 fm −1 and 3.5 fm < r eff < 7 fm, respectively, if samples do not include the feed-down contribution from long-lived particles. We find that the feed-down correction for 0 decay reduces the sensitivity of the correlation function to the detail of the interaction. As a result, we obtain a weaker constraint, 1/a 0 < −0.8 fm −1 . Implication for the signal of existence of H -dibaryon is discussed. Comparison with the scattering parameters obtained from the double hypernucleus may reveal in-medium effects in the interaction.

“…While accelerations of protons and light ions have been investigated, little has been reported on the acceleration of heavy ions. In fact, due to much heavier mass and more choices of charge to mass ratio, heavy ion beams have more advantageous applications related to nuclear science [3], high energy density physics [4], quark-gluon plasmas [5], and others. A large heavy ion accelerator, FAIR [6], is under construction.…”
