Which involves weak interactions?

  1. Aug 3, 2009 #1
    The production of a muon/antimuon pair from an electron and positron
    The production of a neutrino/antineutrino pair from an electron and a positron?

    The only weak interactions I know of are beta-minus decay, beta-plus decay and electron capture. All the sources I've found say they both involve weak interactions :(

    Yes, they both involve the weak interaction. But one of them can proceed through a purely electromagnetic interaction. Which one?
