✦ Synopsis

We show that in high energy nucleus-nucleus collisions the transverse energy or multiplicity distribution Pc, associated to the production of a rare, unabsorbed event C, is universally related to the standard or minimum bias distribution P by the equation U Pc.(-) = -~TP(u), with ~ P(u) = 1 and u = ET or n. Deviations flom this formula are discussed, in particular having in view the formation of the plasma of quarks and gluons. This possibility can be distinguished from absorption on interaction of comovers, looking at the curvature of the J/¢ over Drell-Yan pairs as a function of ET.
