Abstract
J / Psi suppression has been studied by the NA60 experiment in Indium-Indium collisions. A new analysis technique, based only on the J / ? sample, allows to accurately study the centrality dependence of J / ? production. The observed pattern indicates that a suppression is already present in In-In collisions, setting in at ? 90 participant nucleons. A comparison with the available theoretical models is also presented. ? 2006 Elsevier B.V. All rights reserved.File in questo prodotto:
