Il bosone di Higgs è un bosone scalare, elementare e massivo associato al campo di Higgs, che svolge un ruolo fondamentale nel Modello standard conferendo la massa alle particelle elementari tramite il fenomeno della rottura spontanea di simmetria.

In the Standard Model, the Higgs boson is a massive scalar boson whose mass must be found experimentally. Its mass has been determined to be 125.35 ± 0.15 GeV/c 2 by CMS (2022) and 125.11 ± 0.11 GeV/c 2 by ATLAS (2023). It is the only particle that remains massive even at very high energies.
In the Higgs boson's case, the field came first. The Higgs field was proposed in 1964 as a new kind of field that fills the entire Universe and gives mass to all elementary particles. The Higgs boson is a wave in that field. Its discovery confirms the existence of the Higgs field.
The Higgs boson is that particle, and its discovery in 2012 confirmed the BEH mechanism and the Higgs field, allowing researchers to probe ever further in their understanding of matter. Measuring the properties of the Higgs boson in detail is crucial to exploring many outstanding mysteries in particle physics and cosmology, from the wild ...
A questo punto abbiamo iniziato a chiamarlo “bosone di Higgs”. Certamente, rimane ancora da vedere se sia l’unico bosone di Higgs oppure uno dei tanti, come predetto ad esempio dalla supersimmetria. La scoperta del bosone di Higgs si basa sulle misure del suo decadimento in bosoni vettoriali.
The Higgs boson (or Higgs particle) is a particle in the Standard Model of physics. In the 1960s Peter Higgs was the first person to suggest that this particle might exist. On 14 March 2013, scientists at CERN confirmed for the first time that they had found a Higgs particle.
