Resumo

In hydrodynamics, the momentum distribution of particles at the end of the evolution is completely determined by initial conditions. We study quantitatively to what extent anisotropic flow v is determined by predictors such as the initial eccentricity epsilon(n) in a set of realistic simulations, and we also show the importance of nonlinear terms in order to correctly predict v(4). This knowledge will be important for making a more direct link between experimental observables and hydrodynamic initial conditions, the latter being poorly constrained at present. (AU)
