The ratio $v_{2}\{2, |\Delta\eta| > 0.8\} / v_{2}[2, |\Delta\eta| > 0.8]$ for various multiplicity classes in p--Pb collisions at $\sqrt{s_{_{\rm NN}}} = 5.02$~TeV. DPMJET calculations are presented by green shaded lines Hydrodynamic calculations (MUSIC)~ with modified MC-Glauber initial conditions and $\eta/s =$ 0.08 are shown as solid blue lines. | |
