“…At low energies √ s NN < 14.5 GeV, the v 2 3 {2} become consistent with zero in 50-60% peripheral collisions. This result is consistent with the idea of absence of a low viscosity QGP phase in low energy peripheral collisions [26]. For more central collisions, the values of v 2 3 {2} are positive and change little from 19.6 GeV to 7.7 GeV.…”

“…The φ meson may not follow the trend of the other identified hadrons at 7.7 and 11.5 GeV, but more data are needed before any conclusions can be drawn. Hybrid model calculations show that the weak dependence of v 2 (p T ) on the beam energy may result from the interplay of the hydrodynamic and hadronic transport phase [26]. The trianglular flow v 3 is more sensitive to the viscous damping and might be an ideal observable to probe the formation of a QGP and the pressure gradients in the early plasma phase.…”

“…We also note that the ratio involving the shear viscosity is reduced with increasing baryon density, which indicates that the QGP becomes closer to its perfect fluid limit in the baryon dense regime (a similar conclusion was reached within a kinetic approach to a hadronic gas in [105]). Additionally, this has an interesting consequence for the v 2 to v 3 relationship at the Beam Energy Scan and it favors a shorter lifetime of the QGP as argued in [112].…”

Dynamical versus equilibrium properties of the QCD phase transition: A holographic perspective

We employ an Einstein-Maxwell-Dilaton (EMD) holographic model, which is known to be in good agreement with lattice results for the QCD equation of state with (2 + 1) flavors and physical quark masses, to investigate the temperature and baryon chemical potential dependence of the susceptibilities, conductivities, and diffusion coefficients associated with baryon, electric, and strangeness conserved charges. We also determine how the bulk and shear viscosities of the plasma vary in the plane of temperature and baryon chemical potential. The diffusion of conserved charges and the hydrodynamic viscosities in a baryon rich quark-gluon plasma are found to be suppressed with respect to the zero net baryon case. The transition temperatures associated with equilibrium and non-equilibrium quantities are determined as a function of the baryon chemical potential for the first time. Because of the crossover nature of the QCD phase transition even at moderately large values of the chemical potential, we find that the transition temperatures associated with different quantities are spread in the interval between 130 − 200 MeV and they all decrease with increasing baryon chemical potential.

“…Initially, the v 2 3 {2} was found to originate from the initial geometry fluctuations. In addition, recent hybrid model calculations show that the v 2 3 {2} is also very sensitive to a low viscosity QGP phase in the early stage [20]. This motivates us to use v 2 3 {2} to serve as a signature of formation of QGP.…”

Beam energy scan programs in heavy-ion collisions aim to explore the QCD phase structure at high baryon density. Sensitive observables are applied to probe the signatures of the QCD phase transition and critical point in heavy-ion collisions at RHIC and SPS. Intriguing structures, such as dip, peak and oscillation, have been observed in the energy dependence of various observables. In this paper, an overview is given and corresponding physics implications will be discussed for the experimental highlights from the beam energy scan programs at the STAR, PHENIX and NA61/SHINE experiments. Furthermore, the beam energy scan phase II at RHIC (2019-2020) and other future experimental facilities for studying the physics at low energies will be also discussed.
