In high energy heavy-ion collisions, a hot and dense strongly
interacting system of deconfined quarks and gluons (sQGP) is created.
The Beam Energy Scan (BES) program at RHIC was performed to map the QCD
phase diagram. Model calculations suggest, in high energy collisions,
the transition from the hadronic matter to the deconfined state is a
smooth crossover, at lower energies, the phase...
Relativistic hydrodynamics has been a fundamental tool to understand the evolution of matter in heavy-ion experiments at RICH and LHC. Despite the success of second order viscous hydrodynamics in reproducing collective behavior and particle spectra, there are still theoretical shortcomings that may question the validity of the approach in heavy-ion experiments conditions. Large gradients and...
