“…Because of the large statistical uncertainties, it is still not conclusive. It opens a new direction for both experimental and theoretical investigation on directed flow [77]. As discussed above, the v 2 of multi-strange hadrons and φ mesons are more sensitive to the parton level collectivity as their hadronic cross sections are smaller than light flavor hadrons [81][82][83].…”

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.

“…If Ξ directed flow may reveal to be similar to the proton directed flow, it may be evidence of the creation of a deconfined state. We note that AMPT predicts that the Ξ directed flow at midrapidity is the same as the Λ flow [55]. A prediction for the Ξ directed flow within the RQMDv approach will be reported elsewhere.…”

We investigate the sensitivity of the Λ directed flow to the Λ potential in mid-central Au + Au collisions at √ sNN ≈ 3.0-30 GeV. The Λ potential obtained from the chiral effective field theory (χEFT) is used in a microscopic transport model, a vector version of relativistic quantum molecular dynamics (RQMDv). We find that the density-dependent Λ potentials, obtained from the χEFT assuming weak momentum dependence of the potential, reproduce the rapidity and the beam-energy dependence of the Λ directed flow measured by the STAR collaboration in the Beam Energy Scan program. Although the Λ directed flow is insensitive to the density dependence of the potential, it is susceptible to the momentum dependence. We also show that a hydrodynamics picture based on the blast-wave model predicts a similarity of the proton, Λ, and Ξ directed flows, but the directed flow of Ω baryons slightly deviates from other baryons. We also show that the quark coalescence predicts different rapidity dependence of the directed flows for hyperons. These investigations suggest that measurements of a wide range of the rapidity dependence of the directed flow of hyperons may provide important information about the properties of hot and dense matter created in high-energy heavy-ion collisions.

We examine the Λ potential from the chiral effective field theory (χEFT) via the Λ directed flow from heavy-ion collisions. We implement the Λ potential obtained from the χEFT in a vector potential version of relativistic quantum molecular dynamics. We find that the Λ potentials obtained from the χEFT assuming weak momentum dependence reproduce the Λ directed flow measured by the STAR collaboration in the Beam Energy Scan program. While the Λ directed flow is not very sensitive to the density dependence of the potential, the directed flow at large rapidities is susceptible to the momentum dependence. Thus understanding the directed flow of hyperons in a wide range of beam energy and rapidity is helpful in understanding hyperon potentials in dense matter.
