Abstract J/ψ suppression in ultrarelativistic heavy-ion collisions has been predicted to be a signature of the transition from normal hadronic matter to a quark–gluon plasma. Several experiments have been devoted to charmonia production at the CERN/SPS: NA38, NA50 and NA60. All the results obtained so far in proton–proton, proton–nucleus and nucleus–nucleus collisions are summarized. Particular focus is dedicated to the proton–nucleus studies (and comparison to other experiments) needed to determine the normal nuclear absorption, knowledge of which is essential in order to extract the anomalous suppression obtained in nucleus–nucleus collisions.
