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.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

I found this was a good presentation at the time.
There have been some design changes since with the G4ParticleChange class and some method names have changed. Therefore, it's a good idea to crosscheck with current code.
Unfortunately, I couldn't find any obvious place in the G4 documentation or on:
where 'adding a new discrete process' would be explained in lay terms.
Of course, any of the existing G4 physics processes is a good example of what needs to be done. I suggest looking at one of the simpler ones, like photon pair-production, where the primary gamma (in your case the neutrino) disappears and two secondaries (in your case the neutrino reaction products) are generated.
