Closing In: Fermilab Narrows Down the Higgs Mass

Definition of the Higgs Boson and Its Mass

The Higgs boson is a fundamental particle predicted by the Standard Model of particle physics, essential for explaining how other particles acquire mass. This particle arises from the Higgs field, a pervasive energy field that imparts mass to elementary particles through the Higgs mechanism. The precise mass of the Higgs boson is a critical parameter that influences the behavior and interactions of particles within the universe.
