Hydrodynamic event-plane correlations in Pb+Pb collisions at
sqrt(s)=2.76ATeV    [PDF]

Zhi Qiu, Ulrich W. Heinz

The recently measured correlations between the flow angles associated with higher harmonics in the anisotropic flow generated in relativistic heavy-ion collisions are shown to be of hydrodynamic origin. The correlation strength is found to be sensitive to the shear viscosity of the expanding fireball medium.
