- Quark - Wikipedia
Elementary fermions are grouped into three generations, each comprising two leptons and two quarks The first generation includes up and down quarks, the second strange and charm quarks, and the third bottom and top quarks
- Quarks: What are they? | Space
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
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
- What Are Quarks? Building Blocks of Everything
Quarks are tiny, mysterious particles that, together with gluons and leptons, compose all matter in the universe They are the essential constituents of protons, neutrons, and many other particles, and they obey mind-bending rules that challenge our everyday intuition
- 11. 4: Quarks - Physics LibreTexts
In the 1960s, particle physicists began to realize that hadrons are not elementary particles but are made of particles called quarks (The name ‘quark’ was coined by the physicist Murray Gell-Mann, from a phrase in the James Joyce novel Finnegans Wake )
- Quarks - HyperPhysics
Quarks are observed to occur only in combinations of two quarks (mesons), three quarks (baryons) There was a recent claim of observation of particles with five quarks (pentaquark), but further experimentation has not borne it out
- What Are Quarks? » ScienceABC
Quarks were initially theorized as smaller particles that make up protons, and research since then has confirmed their existence By definition, they are subatomic particles that make up every proton and neutron in existence
- 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
