Query: A Poincar\'e-Covariant Parton Cascade Model for Ultrarelativistic
  Heavy-Ion Reactions   We present a new cascade-type microscopic simulation of Nucleus-Nucleus
Collisions at RHIC energies. The basic elements are partons (quarks and gluons)
moving in 8N-dimensional phase space according to Poincar\'e-covariant
dynamics. The parton-parton scattering cross sections used in the model are
computed within perturbative QCD in the tree-level approximation. The $Q^2$
dependence of the structure functions is included by an implementation of the
DGLAP mechanism suitable for a cascade, so that the number of partons is not
static, but varies in space and time as the collision of two nuclei evolves.
The resulting parton distributions are presented and compared to distributions
obtained with the VNI model.
