Strangeness and charm signatures in A+A collisions

Abstract

Two signatures of the quark-gluon plasma - strangeness `enhancement' and J/psi `suppression' - in nucleus-nucleus collisions are critically discussed. A recently developed statistical coalescence model for J/\psi production is presented. The measurements at the RHIC energies are crucial for disentangling the different scenarios of J/\psi formation.
