Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

pi+ has some rare decay modes, specifically e+ nu_e with a branching ratio of (1.230+-0.004)*10^-4. There are others with smaller branching ratios. These are important for simulating backgrounds in some experiments, but they are not implemented in Geant4 9.3 (QGSP_BERT).
Ditto for pi- (pi0?), and possibly other common beam particles (kaons?).
What is the best way to implement these? Can the Geant4 team do it?
