This model generates the final state for anti-xi0 inelastic
scattering. It is one of the HEP models which was derived from
the high energy part of GHEISHA. In the HEP model, the final state
of the hadron-nucleus interaction consists of particles generated at
each of three stages: the initial interaction of the projectile with
a single nucleon in the target nucleus, the cascade of the resulting
particles through the nucleus, and the de-excitation of the remnant
nucleus. Produced particles are grouped into forward-going and
backward-going clusters in the center of mass, where an approximate
energy balance is done before boosting to the lab frame. None of the
three stages is modeled in detail, but instead the hadron energy and
angle distributions are taken from functions whose parameters are the
result of fits to experimental data over a large energy range.
This model gives reliable results when averaged over many events,
or when integral results, such as total particle flux or shower shapes
are desired. There are currently no other models which handle
anti-baryons in this energy range.
For details of this model, see the chapter on Parameterized
Models in the Geant4 Physics Reference Manual.
