Figure 39.34 shows a Feynman diagram for the fundamental process involved in the decay of a free neutron: One of the neutrons down quarks converts to an up quark, emitting a virtual IV boson, which decays into an electron and an anti-electron-neutrino (the only decay energetically possible). Sketch the basic Feynman diagram for the fundamental process involved in each of the following decays:
a) μ- → e- + vμ + e
b) τ- → π- + vτ
c) Δ++ → p + π+
d) K+ → μ+ + vμ
e) Λ0 → p + π-
