29 // G4 Gheisha High Energy (GHE) model class -- header file
30 // H. Fesefeldt, RWTH Aachen 23-October-1996
31 // Last modified: 10-December-1996
32 
33 // A prototype of the Gheisha High Energy collision model.
34 // It includes all Physics Routines from Geant3,
35 // relevant for simulation of hadronic processes
36 // above approx. 20 GeV incident momentum.
37 // Not included are the Physics Routines for
38 // stopping particles, the low energy neutron
39 // slowing down description and the low energy
40 // nuclear reactions a(A,A')b.

45 // Class description:
46 // Each of the high energy parameterized models (e.g. G4HEProtonInelastic)
47 // derives from the G4HEInelastic class. This class contains the various
48 // algorithms needed to implement the interaction. These include
49 // lambda-fragmentation, meson and nucleon cluster formation and decay,
50 // nuclear cascade, and nuclear de-excitation.
51 //
52 // This class is derived from G4HadronicInteraction.
