Question cross section library for antiproton 

Forum: Hadronic Processes
Date: 22 Apr, 2009
From: Tsuguo Aramaki <Tsuguo Aramaki>

Dear all,

Does anybody know what cross section library is used for antiproton elastic and inelastic interaction? (It seems it has not been changed since GEANT3/GHEISHA...) The link below says that the default is G4HadronInelasticDataSet, but I couldn't find any information in G4HadronInelasticDataSet.cc and G4HadronInelasticDataSet.hh. http://geant4.cern.ch/support/proc_mod_catalog/physics_lists/hadronic/QGSP.html

Thanks in advance.

Best regards,

Tsuguo

The anti-proton cross sections are essentially unchanged from those of Geant3/GHEISHA. There the PDG cross sections for pbar-p scattering are used to build up a parameterization of the pbar-nucleus cross sections.

Thank you, Dennis!

I found p-bar p cross section in PDG. But do you happen to know where I can get the information for the parameterization of pbar-nucleus? Is it same as shown in G4HadronNucleonXsc.cc?

Thank you for your time and help!

Look in geant4/source/processes/hadronic/cross_sections/src/G4HadronCrossSections.cc, line 590.

The pbar-p inelastic cross sections are there. The pbar-nucleus parameterizations are also in this file.

Thank you, Dennis!!! I will check it!
