Query: Mechanisms of multiparticle production in heavy ion collisions at high
  energy   In the framework of a microscopic string model inclusive charged particle
distribution and baryon and antibaryon production are described. The emphasis
is put on high energies (RHIC) where shadowing corrections play a crucial role.
Some recent developments on $J/\psi$ suppression at CERN-SPS are also
discussed. Possible consequences for the crucial issue of thermal equilibration
of the produced system are considered.
