Charge Conjugate Reaction

I am having a hard time understanding charge conjugate reactions and finding good examples. attached is a problem I found in my book. I would like any help in understanding how to approach this problem.

What is meant by the 'fine structure constant'? Explain what the fine structure constant tells us about the relative probability of the formation of a three particle event (muon antimuon and photon) compared with the formation of a muon and antimuon pair.

Discuss how Einsteins suggestion that light may be treated as 'particles ' or quanta of energy can explain the observations of the photoelectric effect.
