I correctly asserted that that code was buggy (as I found many bugs in that code myself) in HTTP://HyperNews.SLAC.Stanford.edu/HyperNews/geant4/get/phys-list/545/1.htm= l and it was not contradicted, unless off the forum. A developer of that code sent to me by email: "I'm thankful for you criticism and your opinion, but before we can communicate you should introduce yourself and explain, why you are looking inside the Geant4 implementation of the CHIPS physics package. The present status is: according to the contract with CERN I've implemented in Geant4 a significant part of the CHIPS physics package, which is enough for the independent CHIPS physics list in Geant4. The only implementation, which I did not finish is the implementation of the CHIPS elastic cross-sections. Now I've done it only for nucleons and pions, but during the last three days of my contract I can not manage the implementation of the elastic scattering for kaons, hyperons, and anti-baryons. As I've already demonstrated it even forpions and nucleons, the existing Geant4 cross-sections are about 30% wrong. Everything (including the inelastic cross-sections, which you mentioned) was made in a harry, as I had only one year for the enormously big implementation. That is why you have so many questions.
