Higgs boson
In the early planning studies for the Large Electron–Positron Collider (LEP) at CERN, the Higgs boson played no role. In fact, it does not appear to be mentioned in any of the reports until 1979. The first detailed study examining the possibilities of discovering the Higgs boson at LEP appeared in 1986. Thereafter the search for the Higgs boson became firmly established within the LEP program.
