Etude des effets collectifs dans les collisions d'ions lourds ultrarelativistes

Abstract : The aim of ultrarelativistic heavy ion collisions is to create and to study the quark gluon plasma. These collisions cover a vast field of
both nuclear and high energy physics. In my thesis, I studied two of them: the J/Psi suppression and the collective or "flow" effects.

In this talk, I will only discuss the flow since it is the main topic of my thesis. I shall first present the flow issue, and demonstrate the
limitations of "standard" methods in use since 1985. This point will be illustrate by application to the data published in 1998 by the
NA49 collaboration at CERN. Then I shall present a new method of flow analysis based on a cumulant expansion of multiparticle
azimuthal correlations. It generalizes standard methods and allows more sensitive measurements where previous methods fail. Finally I
shall present my results from the analysis of the latest NA49 data.
