The full quantum mechanical wave function of any hadron must include virtual quark pairs as well as virtual gluons, and allows for a variety of mixings. There may be … Visa mer In particle physics, the quark model is a classification scheme for hadrons in terms of their valence quarks—the quarks and antiquarks which give rise to the quantum numbers of the hadrons. The quark model underlies Visa mer The Eightfold Way classification is named after the following fact: If we take three flavors of quarks, then the quarks lie in the fundamental representation, 3 (called the triplet) of Visa mer • Subatomic particles • Hadrons, baryons, mesons and quarks • Exotic hadrons: exotic mesons and exotic baryons Visa mer Developing classification schemes for hadrons became a timely question after new experimental techniques uncovered so many of them that … Visa mer Since quarks are fermions, the spin–statistics theorem implies that the wavefunction of a baryon must be antisymmetric under … Visa mer chip barclay

One of the few theorists to foresee why two charm quarks might mingle was Jean-Marc Richard, now at the Institute of Physics of the 2 Infinities in Lyon, France. In 1982, he and two colleagues studied a simple quark model and initially found that four quarks would rather form two pairs — mesons.
