Abstract
Measurements of the nucleon form factor and structure function indicate an inhomogeneous distribution of flavor, charge and spin within the nucleon. It is argued that the ordinary constituent quark model can explain the observed inhomogeneity as arising from spin-dependent interaction between quarks in this model. This agreement suggests a specific bound quark picture of the nucleon structure with a moderate diquark correlation.

The “uds” basis was first introduced by J. Franklin, Phys. Rev. 172, 1807 (1968) and recently used in the quark model calculations of Refs. [2] and [5]. In this approach, one notes that by isospin symmetry in the u-d sector it is sufficient to consider the flavor states | uud > and | ddu > for the proton and the neutron, respectively. At the same time one carries out the antisymmetrization (or symmetrization if the color is kept implicit) only with respect to the quantum numbers of the first two identical quarks. Keeping this remark in mind, I will suppress altogether the flavor indices of my wave fun wave functions.
