Quarks in a Surprising Spin Science AAAS
The down quark or d quark (symbol: d) is the second-lightest of all quarks, a type of elementary particle, and a major constituent of matter. Together with the up quark, it forms the neutrons (one up quark, two down quarks) and protons (two up quarks, one down quark) of atomic nuclei. It is part of the first generation of … See more In the beginnings of particle physics (first half of the 20th century), hadrons such as protons, neutrons, and pions were thought to be elementary particles. However, as new hadrons were discovered, the 'particle zoo' … See more • Up quark • Isospin • Quark model See more Despite being extremely common, the bare mass of the down quark is not well determined, but probably lies between 4.5 and 5.3 MeV/c .
