The 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 field.

In back-to-back seminars, physicists from rival experiments within the lab an-nounced the discovery of a new particle, the top quark. A decades-long search for one of the last missing pieces in the Standard Model of particle physics had come to an end. The top quark is the sixth, and quite possibly the last, quark.

Physicists at the Department of Energy's Fermi National Accelerator Laboratory announced on March 2, 1995 the discovery of a subatomic particle called the top quark, the last undiscovered particle of the six-member quark family predicted by current scientific theory.

Dec 26, 2024 · What is a Top Quark? Quarks are elementary particles that constitute matter. They are the building blocks of protons and neutrons, which in turn form the nuclei of atoms. There are six different types of quarks, known as “up,” …

Apr 1, 2015 · The top quark (t) decays into a W boson and a bottom quark (b), and the antitop quark (t) decays into the corresponding antiparticles. The W boson could decay into a pair of quarks that form jets, as described in the text, or it could decay into a …

Nov 15, 2024 · The top quark, also known as the t quark (symbol: t) or truth quark, is an elementary particle and a fundamental constituent of matter.

…of a companion particle, the top quark. This sixth quark type, or “flavour,” was discovered in 1995. Conclusive proof of its existence culminated the search for one of the last missing pieces in the Standard Model of particle physics, which describes …

Mar 2, 2020 · The top quark was the last fundamental particle of matter within the six-member family of quarks predicted by the Standard Model, one that physicists had not yet tracked down. Its discovery would provide strong evidence for the accuracy of the Standard Model.

The top quark is the sixth, and according to the Standard Model, the last to be found. It is one of the fundamental particles of the Standard Model, a "particle zoo" of 6 quarks, 6 leptons, and 4 force-carrying bosons like the photon (the force carrier of light).

Oct 1, 2016 · The top quark is the Q = 2/3, T3 = +1/2 member of the weak-isospin doublet containing the bottom quark (see the review on the “Electroweak Model and Constraints on New Physics” for more information). Its phenomenology is driven by its large mass.
