The Higgs boson is an elementary particle in the Standard Model of particle physics. It was first predicted by Peter Higgs, Robert Brout and Francois Englert in the 1960s, and its existence was confirmed by experiments at the Large Hadron Collider (LHC) at CERN in 2012.

The Higgs boson is responsible for giving mass to other particles through the Higgs mechanism. It is a very rare particle, and only a few have ever been detected at the LHC. However, its discovery was a major milestone in physics, as it confirmed a key prediction of the Standard Model and provided further evidence for the existence of the Higgs field.
