PCPC - a cascade-model to simulate
ultra-relativistic heavy ion collisions:
- The two nuclei A and B are initialized in the cascade's coordinate system
with an energy E greater than several GeV
- To the nuclei are assigned nucleons according to a spatial Woods-Saxon
distribution. The nucleons also get a Fermi-momentum.
- Each nucleon is resolved into partons according to the parton struction
function at a chosen scale.
- The partons move on paths of free particles as defined by the PCD through
space and time.
- Whenever two partons get close enough they scatter using pQCD scattering
cross sections (on tree-level).
- During scattering new partons may be emitted as "soft
- When no further collisions occur the cascade run is over.
- After the run we analyse the phasespace (rapidity and
- A hadronization is under development.
