Abstract. A new data presentation is proposed in order to consider anomalous $J/\Psi$ suppression in ${\mathrm{Pb + Pb}}$ collisions at $P/A=158$ GeV/ $c$ . If the inclusive differential cross section with respect to a centrality variable is available, one can plot the yield of $J/\Psi$ events per Pb–Pb collision as a function of an estimated squared impact parameter. Both quantities are raw experimental data and have a clear physical meaning. As compared to the usual $J/\Psi$ over Drell–Yan ratio, there is a huge gain in statistical accuracy. This presentation could be applied advantageously to many processes in the field of nucleus–nucleus collisions at various energies.
