In 2011, the ATLAS collaboration searched for the Higgs boson in the mass range of 110–600 giga-electron-volts (GeV) in several decay channels, including decay to a pair of photons and decay to four leptons via a pair of Z bosons. By comparing their data with the expected background, the team was able to exclude wide mass ranges in which the Higgs boson could lie, leaving only two small windows between about 116 and 130 GeV. Furthermore, around a mass of 126 GeV, their data show hints of a new particle compatible with being a Higgs boson at the 3σ level. – Urs Heller
