ATLAS and CMS observe a particle consistent with the Higgs boson

4 July 2012

On 4 July 2012, as a curtain raiser to the year’s major particle physics conference, ICHEP 2012 in Melbourne, the ATLAS and CMS experiments present their latest preliminary results in the search for the long-sought Higgs particle. Both experiments have observed a new particle in the mass region around 125-126 GeV. The next step is to determine the precise nature of the particle and its significance for our understanding of the universe.
