Example Events

When both W⁺ and W^- decay to produce a charged lepton and a neutrino we see events containing two (visible) charged leptons and two (invisible) neutrinos:

Notice that in events the two observed leptons are not "back-to-back" as was the case for the events we looked at earlier in which a Z⁰ decays to produce a lepton-antilepton pair. This is because of presence of the neutrinos in the events.
