Example WW (electron-neutrino/two quark) Event

When one W decays to produce an electron and a neutrino, and the other W decays to produce a quark and an antiquark we see events containing an electron, an (invisible) neutrino and two jets: WW (electron-neutrino/two quark)

The neutrino leaves no signals in the detector. However, we can deduce its momentum by using the principal of conservation of momentum
