Energy dependence of v
Neither hadronic nor partonic models can explain the energy dependence of v2 !
Almond-like interaction zone ?
pressure gradient => spatial asymmetry is converted to an asymmetry in momentum space => collective flow
Direct flow
Elliptic flow

24. Event plane angle fluctuation
Au+Au (200 GeV); b=10 fm
Distribution of odd harmonics is practically flat in 0<Ѱn<2π/n; even harmonics are picked at zero.
There is no “tilting” effect due to EM field
V.Konchakovski et al., PR C85, (2012)

25. v2 is reasonably described by PHSD due to an increasing fraction of partonic degrees of freedom !
