Somewhere there is probably a list, or better yet diagram, that shows all of the ways that particles can change into other particles. I have a book called QED written by Feynman that has a few of the more simple ones. However, it is an introduction and doesn't detail how mass, spin, energy, charge, and momentum are conserved.

BTW, it turns out that due to the uncertainties of quantum mechanics that the number of possible particle transformations is infinite leading to infinities showing up in a lot of the equations. These pesky infinities have to be "normalized" out of the equations in order for them to be useful. This is still a somewhat controversial procedure to this day. So QM is still on somewhat shaky ground despite its seeming ability to be very accurate in certain situations.

***I saw an interaction chart like that once, when Antony Garrett’s e8 theory was being discussed. But I can’t find it now...

***Does that mean our universe is a deforming mathematical lie group?
