With it, we can understand the recent OPERA measurement of a tau particle in a muon neutrino beam as well as the early measurements of muon particles in electron neutrino beams.
The theorists proposed that experimenters look for a process in which a Higgs decays into two tau particles, which are like supersized cousins of electrons, while the remainder of the energy from the original proton-proton collision sprays outward in two jets.
At the time of the announcement of the long- sought particle, Vickey was leading a team of 100 scientists searching for the Higgs boson using a signature involving two tau particles (a heavy but unstable cousin of the electron).
