Example WW (lepton-neutrino/lepton-neutrino) 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: WW (lepton-neutrino/lepton-neutrino)

Notice that in WW (lepton-neutrino/lepton-neutrino) 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 WW (lepton-neutrino/lepton-neutrino) events.
