Webof a photon that remains undetected. Our experiment uses pair creation in two separate down-conversion crystals. If a pair is created in the first crystal, the undetected photon passes the Pair production often refers specifically to a photon creating an electron–positron pair near a nucleus. As energy must be conserved, for pair production to occur, the incoming energy of the photon must be above a threshold of at least the total rest mass energy of the two particles created. See more Pair production is the creation of a subatomic particle and its antiparticle from a neutral boson. Examples include creating an electron and a positron, a muon and an antimuon, or a proton and an antiproton. Pair production … See more Pair production is invoked in the heuristic explanation of hypothetical Hawking radiation.
