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/c2 by CMS (2022) [36] and 125.11 ± 0.11 GeV/c2 by ATLAS (2023). It is the only particle that remains massive even at very high energies.
The Higgs boson can't be “discovered” by finding it somewhere but has to be created in a particle collision. Once created, it transforms – or “decays” – into other particles that can be detected in particle detectors. Physicists look for traces of these particles in data collected by the detectors.
10 apr 2024 · The Higgs boson is the fundamental force-carrying particle of the Higgs field, which is responsible for granting other particles their mass. This field was first proposed in the mid-sixties...

Quantum field theory describes the microscopic world of particles very differently to everyday life. Fundamental “quantum fields” fill the universe and dictate what nature can and cannot do. In this description, every particle can be represented by a wave in a “field”, similar to a ripple on the surface of a vast ocean. One example is the photon, t...
When particles interact with one another, they exchange “force carriers”. These force carriers are particles and can also be described as waves in their respective fields. For example, when two electrons interact, they do so by exchanging photons – photons are the force carriers of the electromagnetic interaction.
Another important component of this picture is symmetry. Just like a shape can be called symmetrical if it doesn’t change when rotated or flipped, similar requirements are placed on the laws of Nature. For example, the electrical force between particles with an electrical charge of one will always be the same, irrespective of whether the particle i...

20 apr 2024 · Apr. 10, 2024, 3:14 AM ET (AP) Peter Higgs, physicist who proposed the existence of the 'God particle,' dies at 94. Higgs boson, particle that is the carrier particle, or boson, of the Higgs field, a field that permeates space and endows all elementary subatomic particles with mass through its interactions with them.
The discovery of the Higgs boson opened a whole new branch of particle physics, as researchers began to study its properties. In the Standard Model, the Higgs boson is unique : it has zero spin (making it the only fundamental particle with this characteristic), no electric charge and no strong force interaction.
4 lug 2022 · The Higgs boson is a spin-zero particle. Spin is an intrinsic quantum-mechanical property of a particle, often pictured as an internal bar magnet. All other known fundamental particles...
