Consider the decay of the charmed hyperon Λ(+C) (mass = 2285 MeV/c2) particle made up of the (udc) combination of three quarks.

a.) This particle can decay into a Λo (uds)+Π+(ud) combination. What interaction is responsible for this decay? Explain.

b.) Draw a Feynman diagram that explains this decay.

c.) Create a Feynman diagram for a process where the Λ(+C) (udc) mass = 2285 MeV/c2) decays to a Λo(uds) (mass = 1116 MeV/c2) plus leptons (including neutrinos). The possible charged leptons are the electron (mass = 0.511 MeV/c2), the muon (mass = 106 MeV/c2), and the τ‾ (mass = 1777 MeV/c2) and their antiparticles. Which leptons are possible decay products?
