Description Vladimir.Ivantchenko 2015-02-03 18:34:40 CET
Was checked for CMS needs for all "stable" hadrons and only anti_sigma0 shows the problem. Hadr00 extended example was used.

In my test with Hadr00, both sigma0 and anti-sigma0 return 0 for all energies.
This is the correct behavior because, like the pi0, these particles decay electromagnetically and do not travel far enough to interact once they are produced.    

Also like the pi0, there is no hadronic process for either particle and no hadronic cross section.  In G4HadronCrossSection, the cross section values for both sigma0 and anti-sigma0 are all correctly listed as 0 for all energies.
