1. Draw Feynman diagrams for the following processes and state whether it is a strong, weak or electromagnetic interaction Be sure to get the space and time axes correct. Ensure charge is conserved at each vertex. Each vertex usually consists of two fermions (quarks or leptons) and an exchange boson. Label all particles and get the arrows going the right way on them. In the case of mesons and baryons, show the quark composition. (i) μ΄ →e + De + Um (ii) р⁰ → π¯ +π+ (iii) π° →γ+γ
