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

Similar question,ZapperZ said: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.

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+.
Feynman diagrams are graphical representations of mathematical equations used in theoretical physics to describe interactions between particles. They were developed by physicist Richard Feynman in the 1940s.
Feynman diagrams are used in quantum field theory to calculate the probability of interactions between particles. They are also used to visualize and understand complex physical processes, such as particle collisions.
A complete list of Feynman diagrams allows physicists to accurately calculate and predict the behavior of particles in various interactions. It also serves as a comprehensive reference for all possible particle interactions in a given theory.
The number of Feynman diagrams in a complete list depends on the specific theory and the number of particles involved. In simpler theories, there may be only a few diagrams, while in more complex theories, there could be thousands or even millions of diagrams.
While Feynman diagrams are a powerful tool in theoretical physics, they have some limitations. They do not take into account the effects of gravity and do not work well at extreme energies. Additionally, not all physical phenomena can be accurately described by Feynman diagrams.
