Top quark - Wikipedia
WEBThe top quark, sometimes also referred to as the truth quark, (symbol: t) is the most massive of all observed elementary particles.It derives its mass from its coupling to the Higgs boson.This coupling y t is very close to unity; in the Standard Model of particle physics, it is the largest (strongest) coupling at the …
Higgs boson: The 'God Particle' explained - Space.com
WEBApr 10, 2024 · The Higgs boson is a fundamental particle discovered on July 4, 2012, by researchers at the Large Hadron Collider (LHC) located at CERN, Switzerland.
A portrait of the Higgs boson by the CMS experiment ten years
WEBJul 4, 2022 · At the LHC, the production of Higgs bosons is dominated by gluon–gluon fusion (ggH) proceeding via a virtual top quark loop.
Even the heaviest particles experience the usual quantum …
WEB1 day ago · But the sixth and final quark, the “top”, is a monster: slightly heavier than a tungsten atom, and 184 times the mass of a proton. No one knows why the top quark is so massive .
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.
Large Hadron Collider's ATLAS finds entanglement in pairs of top …
WEB18 hours ago · The ATLAS experiment at the Large Hadron Collider, which studies top and antitop quarks produced in proton collisions at 13 TeV, has made the highest-energy observation of entanglement to date ...
Homing in on the Higgs boson's interaction with the charm quark
WEBMar 11, 2022 · In their latest studies, using data from the second run of the LHC, the two teams searched for the decay of the Higgs boson into a charm quark and its antimatter counterpart, the charm antiquark. In the Standard Model, this decay is relatively rare, occurring only 3% of the time.
Higgs Decay into Bottom Quarks Seen at Last - Physics
WEBSep 17, 2018 · The Higgs mechanism is the linchpin of this theory, explaining not only the masses of the W and Z bosons but also providing a way to account for the masses of the fundamental fermions—the quarks and charged leptons.
Sizing Up the Top Quark’s Interaction with the Higgs - Physics
WEBJun 4, 2018 · The top quark is similar to the up quark found in ordinary matter, but it is about one hundred thousand times heavier—with a mass close to that of a tungsten nucleus. The Higgs boson, meanwhile, is the only fundamental particle observed so far that doesn’t have the intrinsic property of spin.
Quarks show that quantum entanglement holds at high energies
WEB1 day ago · This is the point at which the top-quark pair rapidly decayed, and it most frequently involved the production of a bottom quark, an anti-bottom quark and two W bosons, particles that transmit the ...
