TL;DR: The NA49 experiment has been enhanced with a systematic study of impact parameter and projectile size dependence, as well as the inclusion of the more elementary p+p and p+A interactions as discussed by the authors.

TL;DR: In this paper, the yields in Pb-Pb interactions are presented as a function of collision centrality and compared with those obtained from p-pb collisions at 158 A GeV/c.
Journal ArticleDOI
An alternative mechanism of Jψ suppression in heavy ion collisions
TL;DR: In this article, it was shown that the suppression observed in high energy oxygen-uranium collisions by the NA38 Collaboration at CERN need not imply that the quark-gluon plasma was produced.

TL;DR: An upper limit on genuine nonstatistical fluctuations is derived, which could be related to a first- or second-order QCD phase transition and is shown to be very small.
