What exactly are we doing when we “invent” Feynman Diagrams?

Hey mate ^_^
Factors for vertices are always easy, you read them from the Hamiltonian.....
External lines are harder, you get these from either seeing the pattern or, as said already, formally by LSZ.....
Everything else is basically always the same....

Hey Mate
Actually, both of these processes are physically allowed, but the diagrams representing them are flawed. In principle, if the diagrams were drawn correctly, we could use the rules of quantum field theory to calculate the probability amplitudes to them, as you wish, but these would depend on parameters such as the energy the particles were collided at, and wouldn't yield pure numbers. I suspect you're looking for something less technical.
