Abstract
A comparative study is made of scalar versus vector forms of confinement (both with quadratic shapes) to the extent they affect the properties of bound qqq (N, Δ) and NN (6q) scattering systems. The vector form (≈γμ(1)γμ(2)) exhibits some additional structure (Qr, J . S) in the confinement potential which is sensitive to the N, Δ properties, but its effect on NN phase shifts is quite small. The scalar form, being free from this additional structure, does not show such sensitivity to either system. Both forms reproduce the observed S-wave phase shifts quite well.
