But it is not exactly colour as we know it. The prize has been scooped for work on 'colour interaction': the poetic way in which physicists refer to the strong nuclear force, which binds together the fundamental particles called quarks that make up protons and neutrons in an atomic nucleus...
Trios of quarks make up protons and neutrons (shown), but five quarks together would be extremely unusual.© SPL Physicists have come home empty-handed from a thorough hunting expedition for pentaquarks. The lack of evidence has led some to doubt that these odd subatomic particles, first sigh...

thequarksmay arrange and combine themselves differently in situations that would be instantly unstable in any other environment.—Paul Sutter,Space.com, 28 Apr. 2025As things cooled,quarksformed and then condensed into protons and neutrons.—Quanta Magazine, 2 Apr. 2025See All Example Sentences for...
A quark is an elementary particle and a basic component of matter. Protons and neutrons, the particles that make up the nucleus of an atom, are made up of quarks. One of the four fundamental forces of existence, the strong force, holds quarks ...
Colliding high-energy electrons, and other particles, with protons and neutrons thus gives us insight into the structure of neutrons and protons. Below a certain energy the electrons have a wave-length too large to 'probe' the internal structure of the nucleon and elastic collisions (like those...
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,”“down,”“charm,”“strange,”“top,” and “bottom.” These particles are held ...
The building blocks ofatomic nucleiareprotonsandneutrons, which are themselves made of even more fundamental particles:quarks and gluons. These particles interact via the “strong” force, one of the four fundamental forces of nature. They make up the nuclei at the heart of everyatom...
Matter is made of elementary particles, and the Standard Model of particle physics states that these particles occur in two families: leptons (such as electrons and neutrinos) and quarks (which make up protons and neutrons). Under the Standard Model, these two families are totally distinct, with...
Strong force, a fundamental interaction of nature that acts between subatomic particles of matter. The strong force binds quarks together in clusters to make more-familiar subatomic particles, such as protons and neutrons. It also holds together the atom
