dc.descriptionThe measurement of azimuthal distributions in nucleus-nucleus collisions relies upon the assumption that azimuthal correlations between particles result solely from their correlation with the reaction plane (i.e. flow). We show that at SPS energies, the ansatz is no longer valid, and two-particle correlations due to momentum conservation, final state interactions or resonance decays become of the same order as those arising from flow. This leads us to introduce new methods to analyse collective flow, based on a cumulant expansion, which enable to extract smaller values than those accessible to the standard analysis.
