نویسنده
چکیده
The quark flavor and spin distributions in octet baryons are calculated both in the SU(6) quark spectator diquark model and in a perturbative QCD (pQCD) based model. It is shown that the Λ has the most significant difference in flavor structure at large x between the two models, though the flavor and spin structure of other baryons can also provide tests of different models. The Drell-Yan process for Σ± beams on isoscalar targets can be used to test different predictions concerning the valence quark flavor structure of the Σ±. PACS numbers: 14.20.-c, 12.38.Bx, 12.39.Ki, 13.85.-t

We treat the baryon as a composite system made out of a " core " of three quarks (as in the standard quark model) surrounded by a " sea " (of gluons and q ¯ q-pairs) which is specified by its total quantum numbers like flavor, spin and color. Specifically, we assume the sea to be a flavor octet with spin 0 but no color. The general wavefunction for spin 1/2 baryons with such a sea component is ...

It is shown that perturbative QCD (pQCD) and the SU(6) quark-diquark model give significant different predictions concerning the flavor and spin structure for the quark distributions of the Λ-baryon near x = 1. Detailed predictions for the ratios u(x)/s(x) of unpolarized quark distributions, ∆s(x)/s(x) of valence strange quark, and ∆u(x)/u(x) of valence up and down quarks of the Λ are given fro...

We review the Skyrme model approach which treats baryons as solitons of an effective meson theory. We start out with a historical introduction and a concise discussion of the original two flavor Skyrme model and its interpretation. Then we develop the theme, motivated by the large N C approximation of QCD, that the effective Lagrangian of QCD is in fact one which contains just mesons of all spi...

Spin-flavor symmetry breaking in the levels of excited Baryons are studied to leading order in the 1/N c expansion. This breaking occurs at zeroth order. For non-strange Baryons with a single quark excited, it is shown that to first order of perturbation theory the breaking is given by one 1-body operator (spin-orbit), and three 2-body operators, all involving the orbital angular momentum of th...
