One of the main fields of interest of this research group lies in simulating heavy ions collisions with cascade models. For this purpose it is necessary to understand the dynamics of interacting point particles at high energies. The description of this dynamics developed by our group is named Poincaré-Covariant-Dynamics (PCD).
An introduction to PCD can be found in the following papers:

Poincaré-Covariant Parton Cascade (PCPC)

On the basis of PCD we developed a cascade code to simulate ultra-relativistic heavy ion collisions. This code, which is available in the OSCAR-Archive , is described in more detail in:
             V. Börchers, S. Gieseke, G./ Martens, J. Meyer, C. Noack,
                    Nucl.Phys. A 661 (1999),587c [ contrib.paper at Quark Matter '99 (Torino) ]
                         ( hep-ph/9907215)
                    Phys. Rev. C 62, 064903 (2000)
                         ( hep-ph/0006038)

             Some remarks concerning the causality of parton cascades were presented (ccn) on a poster at Quark Matter '04 (Oakland)
                         ( hep-ph/0312365)

Another variant of this approach (based on the concept of constraint dynamics) is used in

and leads to an alternate parton cascade model:

A confined parton cascade (CPC)
