Hi Donghee,

I explained difference between ftfp and ftfb in the
file README.txt in the FtfEvtGen folder.

I do it again.

ftfp is the FTF + Preco model.
ftfb is the FTF + Binary cascade model.

FTF is taken from Geant4 lib.
Preco and Binary Cascade model are also Geant4 models and added
for low energy secondary particles interactions in the nucleus.
Binary Cascade model takes into account all cascading processes.
Preco model is simplified model, taking into account only
absorption processes.

For Pbar-P interactions use ftfp.

For Pbar-Nucleus interactions, one can use ftfp or ftfb.
There will be difference between ftfp and ftfb calculations,
(especially for heavy nuclei)
but ftfp works faster than ftfb. However, ftfb gives more
precise results for secondary nucleons.

Other models(QGSp, QGSb, Bertini,...)are not aimed for
Pbar-P or Pbar-Nucleus processes. Corresponding task can
be crash.

Best regards
Aida
