“…One important element of such an approach is that when we switch from the hydrodynamic phase to the hadronic phase, the EoS of lQCD and that of the hadron resonance gas should be consistent otherwise the conservation of energy and momentum is compromised (see Ref. [195]). It is also pointed out that the hadronic mass spectrum affects the final state collective flow parameters [196].…”

We review several facets of the hydrodynamic description of the relativistic heavy ion collisions, starting from the historical motivation to the present understandings of the observed collective aspects of experimental data, especially those of the most recent RHIC and LHC results. In this report, we particularly focus on the conceptual questions and the physical foundations of the validity of the hydrodynamic approach itself. We also discuss recent efforts to clarify some of the points in this direction, such as the various forms of derivations of relativistic hydrodynamics together with the limitations intrinsic to the traditional approaches, variational approaches, known analytic solutions for special cases, and several new theoretical developments. Throughout this review, we stress the role of course-graining procedure in the hydrodynamic description and discuss its relation to the physical observables through the analysis of a hydrodynamic mapping of a microscopic transport model. Several questions to be answered to clarify the physics of collective phenomena in the relativistic heavy ion collisions are pointed out.

“…It may indicate that the flow profile generated in the hydrodynamic simulation with Glauber model initial conditions is only approximate or that contributions of the pre-equilibrium flow or rescattering stage are noticeable [21]. Other effects could be also be important for the interferometry in small systems [22].…”

The femtoscopy correlation radii for d-Au collisions at 200 GeV are calculated in the hydrodynamic model and compared to data of the PHENIX Collaboration. For asymmetric systems, such as d-Au or p-Pb collisions, the correlation radius R0Ut.]0ng is estimated and predicted to be nonzero. It appears due to different hfetimes of the parts of the fireball at positive and negative rapidities. Azimuthally sensitive Hanbury Brown-Twiss analysis with respect to the second-order event plane shows a significant angular dependence of the radii. It reflects the strong azimuthal asymmetry of the d-Au source geometry and flow for central interactions.

Initialization of hydrodynamics in relativistic heavy ion collisions with an energy-momentum transport model

A key ingredient of hydrodynamical modeling of relativistic heavy ion collisions is thermal initial conditions, an input that is the consequence of a prethermal dynamics which is not completely understood yet. In the paper we employ a recently developed energy-momentum transport model of the prethermal stage to study influence of the alternative initial states in nucleus-nucleus collisions on flow and energy density distributions of the matter at the starting time of hydrodynamics. In particular, the dependence of the results on isotropic and anisotropic initial states is analyzed. It is found that at the thermalization time the transverse flow is larger and the maximal energy density is higher for the longitudinally squeezed initial momentum distributions. The results are also sensitive to the relaxation time parameter, equation of state at the thermalization time, and transverse profile of initial energy density distribution: Gaussian approximation, Glauber Monte Carlo profiles, etc. Also, test results ensure that the numerical code based on the energy-momentum transport model is capable of providing both averaged and fluctuating initial conditions for the hydrodynamic simulations of relativistic nuclear collisions.
