Hello, Im trying to find out if, since an electron positron pair can anhillate to produce a muon-anti muon pair by the weak interaction, can the same thing occur for the production of an electron/anti-electron pair? Or would it just happen by the electromagnetic force? Or both, with the weak being supressed? And are the photons/ Z0 bosons involved real or virtual? I feel as if I am asking a question I should know the answer to and being silly, but any help would be appreciated! Thanks!
