// G4 Gheisha High Energy model class -- header file

// A prototype of the Gheisha High Energy collision model.

// Class description:
// High energy parameterized model for Xi0 inelastic scattering.  This
// class is responsible for producing the final state of the interaction and
// is typically valid for incident Xi0 energies above 20 GeV.  This
// physics may be invoked by registering an instance of the class with
// G4XiZeroInelasticProcess in the user's physics list.
//
// This class is derived from G4HEInelastic which in turn is derived from
// G4HadronicInteraction.
