Higgs boson - Wikipedia
WEBIn 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) [36] and 125.11 ± 0.11 GeV/c 2 by ATLAS (2023). It is the only particle that remains massive even at very high energies.
What Is the Higgs Boson? - Discover Magazine
WEB3 days ago · It also interacted with an entire class of particles known as leptons, which include electrons and quarks – the building blocks of matter. Specifically, the interaction with the Higgs boson is responsible for the mass of these particles. In other words, without the presence of the Higgs boson, these particles would be massless.
The two most massive quarks put the spotlight on the Higgs boson
WEBThe two heaviest known elementary particles, the top (t) quark and the Higgs (H) boson, are deeply connected. They provide an essential probe of the Standard Model (SM) of particle physics, our best attempt so far at describing the fundamental particles and their interaction, and of hypothetical new physics beyond the SM.
The Higgs boson: What makes it special? - CERN
WEBMar 30, 2020 · When two protons collide within the LHC, it is their constituent quarks and gluons that interact with one another. These high-energy interactions can, through well-predicted quantum effects, produce a Higgs boson, which would immediately transform – or “decay” – into lighter particles that ATLAS and CMS could observe.
The Higgs boson: a landmark discovery - ATLAS Experiment at CERN
WEBPhysicists describe particle interactions using the mathematics of quantum field theory, in which forces are carried by intermediate particles called bosons. Photons, for example, are bosons carrying the electromagnetic force. In 1964, the only mathematically consistent theory required bosons to be massless.
The Higgs boson, ten years after its discovery - CERN
WEBTen years ago, on July 4 2012, the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) announced the discovery of a new particle with features consistent with those of the Higgs boson predicted by the Standard Model of particle physics.
