Thank you for reporting bugs. particles-V10-00-02 is the bug fixed tag including updating particle properties. (Please wait tags for 9.6 patches) |
Created attachment 256 [details] The patch to fix the problem in Geant4 9.6 Federico Carminati has found three heavy antibaryons which have wrong properties: - anti_lambda_b : it has incorrectly assigned "+1" baryon number instead of "-1"; moreover, it decays incorrectly to "lambda_b" instead of "anti_lambda_b". - anti_lambda_c : it has incorrectly assigned "+1" baryon number instead of "-1"; moreover, it decays incorrectly to "lambda_c" instead of "anti_lambda_c". - anti_sigma_b0 : it decays incorrectly to "lambda_b" instead of "anti_lambda_b". These three problems are fixed by the patch provided in attachment. To apply it, copy it at the top level of Geant4 (where source/ appears as a subdirectory), and then do: patch -p1 < G4corr9.patch Note: it should be applied to the following versions of Geant4: - G4 9.6 (so that it will be included in the next patch, 9.6.p03); - G4 10.0 (so that it will be included in the next patch, 10.0.p01); - development version (so that it will be included in the next reference tag, 10.0.ref02).
