The CMS experiment awaits LHC Run 3 to explore several analyses showing small disagreements with theory expectations

The year 2000 was set to be the last year of running for CERN’s Large Electron–Positron (LEP) collider, and it ended dramatically

The direct discovery of the W and Z bosons at the SppS in 1983 provided solid experimental support for the existence of the Higgs boson

The resultant particles quickly spread around the globe, potentially influencing Earth’s climate on an intercontinental scale

The observation provides direct experimental access to the mass of an elementary particle known as the charm quark

As the various breakthroughs of the 1970s gradually consolidated the Standard Model, the Brout–Englert–Higgs field and its boson emerged as the most promising theoretical model to explain the origin of mass

The collaboration has put the seesaw model of neutrino mass to a new test

The Higgs boson holds the record (48 years) among elementary particles for the time between prediction and discovery, going from an esoteric technicality to commanding the global spotlight at the world’s most powerful collider

Precise knowledge of the top-quark mass is of paramount importance to understand our world at the smallest scale

The finding may help determine whether or not any antimatter seen by experiments in space originates from dark matter
