Abstract :
Using a hadron-string cascade model LUCIAE, the φ-meson production in nuclear collisions (p+Pb and Pb+Pb) and elementary collisions p+p were studied systematically. Within the framework of the model, the experimentally measured φ enhancement in p+Pb and 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.
