Why is it easier to see the properties of the c, b, and t quarks in mesons having composition W- or t $\overline{A}$ rather than in baryons having a mixture of quarks, such as udb? Two protons each of mass 1.67x10-27 kg an...
In the general case, the exception being the pseudoscalar mesons, the mixing process is of small amplitude. It is then the mass hierarchy of quarks which governs essentially the composition of neutral mesons.doi:10.1007/BF02730189Ch. de la Vaissière...

In this work, we calculate the magnetic moments of thePψN0states andPψΔ0states with valence quark contentc¯cuddin molecular model, diquark–diquark–antiquark model and diquark–triquark model, as well as the transition magnetic moments in the molecular model. At the same time, we al...
Noun1.down quark- a stable quark with an electric charge of -1/3 and a mass 607 times that of an electron quark- (physics) hypothetical truly fundamental particle in mesons and baryons; there are supposed to be six flavors of quarks (and their antiquarks), which come in pairs; each ...
摘要: Particle ratios in the photon initiated inclusive reactions at fixed angles are studied in the two way quark-cascade model based on simple quark counting. The quark content of the incident photon is shown to be essential to fit the particle composition data....

The latter transition may be induced by a relatively small change in compound composition (cf. the behavior of La2 − xSrxO4 or YBa2Cu3O7 − x as a function of x). It is quite interesting to note that oxides such as YBa2Cu3O7 − x may be synthesized in either insulating (x ...
