The Tau Neutrino Has Finally Been Seen. Has the Higgs also been Seen?

OCT 01, 2000
The existence of the third neutrino was hardly in doubt. But it took the sub‐micron precision and electronic sophistication of a modern photo‐emulsion target to find the decay of its telltale collision product.

Twenty‐five years after the discovery of the tau lepton ±), its neutrino τ) has at long last been detected. At a Fermilab seminar in July, Byron Lundberg of the international DONUT (Direct Observation of Nu Tau) collaboration reported that five months of exposing a photographic‐emulsion target to an intense neutrino beam from the Tevatron had netted four identifiable ντ interactions.
