Nature of problem:
To describe the complete interaction dynamics and the resulting final state in deep inelastic lepton-nucleon scattering. Simulated events facilitate studies of the hadronic final state with, e.g., jets and rapidity gaps.
The problem is naturally divided into several phases: the scattering of the lepton on the (anti)quark in the nucleon given by leading order electroweak matrix elements in the QCD-improved parton model, leading order QCD matrix elements, higher order QCD emissions approximated by leading logQ**2 initial and final state parton showers, non-perturbative QCD interactions described by a model for soft colour interactions and the Lund string hadronization model. All are treated with Monte Carlo simulation methods, resulting in a complete account for the interaction dynamics and the final state of observable particles.
Polarized nucleons are not treated.
The CERNLIB packlib, mathlib and kernlib libraries are needed.
10-100 events per second on a DEC AlphaStation 200 depending on process simulated and completeness of simulation.
