The quark structure of hadrons
Webb24 feb. 2024 · Let us start our discussion for the effective theories for heavy quarks and hadrons. When the heavy quark mass m Q is much larger than the typical low energy scale in QCD, it is a good approximation to neglect the excitation of heavy antiquark and to change the theory simpler than the original QCD. In the heavy quark limit m Q →∞, the … WebbParton distributions in impact parameter space, which are obtained by Fourier transforming GPDs, exhibit a significant deviation from axial symmetry when the target and/or quark are transversely polarized. Connections between this deformation and transverse single-spin asymmetries as well as with quark–gluon correlations are discussed. The sign of …

Webb4 mars 1999 · The following lectures concern with the quark structure of hadrons made up from light quarks. The symmetries of strong interaction were the only instruments used for the description of this structure. The models of hadrons (there are a lot of them) were not considered. There was not also considered the structure of hadrons with heavy quarks. …

While the quark model is derivable from the theory of quantum chromodynamics, the structure of hadrons is more complicated than this model allows. 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 hadrons which lie outside the quark model. Among these are the glueballs (which contain only valence gluons), hybrids (which contain valence quarks as well as gluons) a… Webbför 2 dagar sedan · Anisotropic flow and the valence quark skeleton of hadrons.
