elementary components, quarks. In the quark model for hadrons, the neutron is composed of one up quark (charge ⁠++ 2 /3⁠ e) and two down quarks (charge ⁠−+ 1 /3⁠ e)...

Protons and neutrons are not elementary particles; each is composed of three quarks. The chemical properties of an atom are mostly determined by the configuration...

family of subatomic particle made of three up or down quarks (u or d quarks), the same constituent quarks that make up the more familiar protons and neutrons...

entanglement has been demonstrated experimentally with photons, electrons, top quarks, molecules and even small diamonds. The use of entanglement in communication...

in 1947. By the 1970s, the quark model had been developed, by which the mesons and nucleons were viewed as composed of quarks and gluons. By this new model...
