Quarks: What are they? | Space
2022年11月1日 · Quarks are elementary particles that are the building blocks of all visible matter in the universe. Explore them in more detail here.
Quark | Definition, Flavors, & Colors | Britannica
2024年10月30日 · quark, any member of a group of elementary subatomic particles that interact by means of the strong force and are believed to be among the fundamental constituents of matter.
DOE Explains...Quarks and Gluons | Department of Energy
Quarks and gluons are the building blocks of protons and neutrons, which in turn are the building blocks of atomic nuclei. Scientists’ current understanding is that quarks and gluons are indivisible—they cannot be broken down into smaller components.
11.4: Quarks - Physics LibreTexts
Six known quarks exist: up (u), down (d), charm (c), strange (s), top (t), and bottom (b). These particles are fermions with half-integral spin and fractional charge. Baryons consist of three quarks, …
The Standard Model - CERN
All matter around us is made of elementary particles, the building blocks of matter. These particles occur in two basic types called quarks and leptons. Each group consists of six particles, which are related in pairs, or “generations”.
Quarks - HyperPhysics
Quarks. Quarks and Leptons are the building blocks which build up matter, i.e., they are seen as the "elementary particles". In the present standard model, there are six "flavors" of quarks. They can successfully account for all known mesons and baryons (over 200).
Subatomic particle - Quarks, Antiquarks, Gluons | Britannica
Subatomic particle - Quarks, Antiquarks, Gluons: The baryons and mesons are complex subatomic particles built from more-elementary objects, the quarks. Six types of quark, together with their corresponding antiquarks, are necessary to account for all the known hadrons.
DOE Explains...the Standard Model of Particle Physics
The Standard Model of Particle Physics is scientists’ current best theory to describe the most basic building blocks of the universe. It explains how particles called quarks (which make up protons and neutrons) and leptons (which include electrons) make up all known matter.
Fifty years of quarks - CERN
In 1964, two physicists independently proposed the existence of the subatomic particles known as quarks. Physicists Murray Gell-Mann and George Zweig were working independently on a theory for strong interaction symmetry in particle physics.
quark summary | Britannica
quark, Any of a group of subatomic particles thought to be among the fundamental constituents of matter—more specifically, of protons and neutrons. The concept of the quark was first proposed by Murray Gell-Mann and George Zweig (b. 1937); its name was taken from James Joyce ’s novel Finnegans Wake.
