Abstract
We point out that the data on the onset of anomalous J/ψ suppression as a function of nucleon numbers A and B could provide information on the dynamics of nuclear interactions. In particular the models of anomalous J/ψ suppression by Blaizot and Ollitrault (BO) and by Kharzeev, Lourenço, Nardi and Satz (KLNS) are based on different assumptions on the dynamics of nuclear collisions and lead to different predictions of the dependence of the onset of anomalous J/ψ suppression on nucleon numbers of colliding nuclei. The data on this onset as function of A and B could become a tool for the study of the dynamics of nuclear collisions and bring further evidence on J/ψ suppression by new form of hadronic matter, possibly quark–gluon plasma. In particular we propose to study J/ψ suppression in A+Pb interaction with nucleon number of A between 58 and 73 or a bit higher.
