The particle-physics breakthrough that paved the way for the Higgs boson
WEBJul 19, 2023 · According to the unified electroweak theory, there are two types of neutral-current process, so called because they involve the neutral Z boson: leptonic and hadronic processes.
Thirty years of the Z boson - CERN
WEBJun 1, 2013 · The physicists began sifting through collision data in 1981, and just two years later they found the first unambiguous signals of the Z boson. The discovery of Z bosons was an extraordinary technical triumph, confirming a critical aspect of the Standard Model.
WEBPrecision measurements at the Z-boson resonance using electron–positron colliding beams began in 1989 at the SLC and at LEP. During 1989–95, the four LEP experiments (ALEPH, DELPHI, L3, OPAL) made high-statistics studies of the production and decay properties of the Z.
