The nucleon spin structure in a simple quark model
نویسنده
چکیده
We investigate the spin structure of the nucleon in an extended Jaffe-Lipkin quark model. In addition to the conventional 3q structure, different (3q)(QQ̄) admixtures in the nucleon wavefunction are also taken into account. The contributions to the nucleon spin from various components of the nucleon wavefunction are discussed. The effect due to the Melosh-Wigner rotation is also studied. PACS numbers: 12.39.-x, 13.60.Hb, 13.88.+e, 14.20.Dh

THE ROLE OF QUARK POLARIZATION IN HEAVY QUARK FRAGMENTATION
We calculate the exact fragmentation functions for c and b quark fragmentation taking into account the spin orientation of the initial heavy quark in the form of analytical and rather simple expressions. Our calculations show that spin orientation may have an important effect on the fragmentation spectrum. This effect is more striking in the cases of c ?D, D*; c? ? , ? , and ?B , B *.
متن کاملA QUARTIC POTENTIAL FOR THE NUCLEONIC QUARKS
We assume that each valence quark in a nucleon is in a phenomenological modified harmonic oscillator potential of the form: ( l+yo) (ar +br+cr +dr ), where a, b, c and d are constants and ? is one of the Dirac matrices. Then by making use of a suitable ansatz, the Dirac equation has a very simple solution which is exact. We then have calculated the static properties of the nucleon in the ...
متن کاملIs Nucleon Spin Structure Inconsistent with Constituent Quark Model?
Hadron structure studies might be traced back to Fermi-Yang [1] and Sakata models [2]. Gell-Mann [3] and Zweig [4] proposed the quark model of hadrons. Lepton-nucleon deep inelastic scattering (DIS) [5] verified the quark structure of hadrons. However the quark revealed in DIS is found to be different from the quark as a carrier of SU(3) symmetry in Gell-Mann-Zweig model. The former is almost a...
متن کاملLight flavor sea-quark asymmetry for the spin-dependent distribution functions of the nucleon
The theoretical predictions of the chiral quark soliton model for the unpolarized and longitudinally polarized structure functions of the nucleon are compared with recent high energy data. The theory is shown to explain all the qualitatively noticeable features of the existing experiments, including the light flavor sea-quark asymmetry for the unpolarized distribution functions established by t...
متن کاملPresence of the Universal Substructures in the Hadrons – Constituent Quarks
The universality of single-spin asymmetry on inclusive π-meson production is discussed. This universality can be related to the hadron substructure— constituent quarks in the frame of the quark model for U-matrix. Polarization experiments give us an unique opportunity to probe the nucleon internal structure. While spin averaged cross-sections can be calculated within acceptable accuracy, curren...
