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 ev","authors_text":"C.
