Abstract
Using a hadron-string cascade model LUCIAE, the meson production in heavy ion collisions (Pb+Pb) and elementary collisions (p+p) were studied systematically. Within the framework of the model, the experimentally measured enhancement in Pb+Pb over p+p collisions can be mostly explained by the collective effects in the gluon string emission and the reduction of the s-quark suppression.
