Collective properties from RHIC to LHC

The collectivity exhibited amongst particles produced in Nucleus-Nucleus collisions shows similar features across a range of center-of-mass energies from 7.7 GeV to 2.76 TeV. This similarity is considered surprising to many in the field and the question arises, why don't we see the turn-off of the QGP. In this talk I will review the relevant measurements and point out that data show interesting features indicative of the disappearance of QGP in lower energies and smaller systems.
