... Pair production is the creation of an elementary particle and its antiparticle, for example an electron and its antiparticle, the positron, a muon and antimuon, or a tau and antitau. Usually it occurs when a photon interacts with a nucleus, but it can be any other neutral boson, interacting with a n ...
