J / ψ suppression has been studied by the NA60 experiment in Indium-Indium collisions. A new analysis technique, based only on the J / ψ sample, allows to accurately study the centrality dependence of J / ψ 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.
