Description

Hydrodynamical models must be able to reproduce data not only in average for a given centrality class but for each event. In particular they must reproduce the scaled $v_n$ distributions obtained by ATLAS [1,2] and ALICE [3]. These distributions are independent of medium properties such as viscosity, and so directly probe the initial conditions.

They in fact provide a strong test for initial condition models: many models (e.g. Glauber and MC-KLN) can be ruled out and so far only two models lead to satisfactory results [4,5]. In this work, we show that NeXus initial conditions also provide reasonable results for scaled $v_n$ distributions at LHC energies and make predictions for RHIC top energy.
