Abstract

Enhanced strangeness production in nuclear collisions has been proposed as a possible signature of quark-gluon plasma formation: in particular, the ø production might increase. We find however that the observed enhancement of the ø/(ϱ 0 + ω) ratio observed in relativistic heavy ion collisions at CERN, might be due to the smaller size of the ø absorption cross section and that the enhancement of the ø to continuum ratio could be an artifact of the p t cutoff applied to the data. We suggest that high p t vector mesons at midrapidity, once created in primary collisions, can only be depleted by absorption in secondary collisions and not recreated: no real enhancement of ø production would be expected and in fact none may be needed to explain the data.
