Higgs boson

The Higgs boson or Higgs particle is an elementary particle initially theorised in 1964,^[7] and tentatively confirmed to exist on 14 March 2013.^[8] The discovery has been called "monumental"^[9][10] because it appears to confirm the existence of the Higgs field,^[11][12] which is pivotal to the Standard Model and other theories within particle physics. In this discipline, it explains why some fundamental particles have mass when the symmetries controlling their interactions should require them to be massless, and—linked to this—why the weak force has a much shorter range than the electromagnetic force. Its existence and knowledge of its exact properties are expected to impact scientific knowledge across a range of fields, and should eventually allow physicists to determine whether the Standard Model or a competing theory is more likely to be correct, guide other theories and discoveries in particle physics, and—as with other fundamental discoveries of the past—potentially over time lead to developments in "new" physics,^[13] and new technologies.^[14][15]
