Is there an on-line list of all possible Feynman diagrams for all the known particles?

There are an infinite number of interactions, so how can there be such a list? Even for ONE, particle, there can be an infinite sum of higher-order self-energy interactions, meaning you have an infinite number of Feynman diagrams representing each term.

This is a puzzling question.

Similar question,
Is there a list, taking the known elementary particles and know Forces showing the know pathways of making composite and elementary particles?
for example. p -> n + e- + electron neutrino by a W+.

Actually, no, this is not a similar question. You need to post this in the high-energy physics forum.

BTW, p -> n + e- + ν violates conservation of charge.
