SCALAR SEA CONTRIBUTIONS TO SPIN 1 2 BARYON STRUCTURE AND MAGNETIC-MOMENTS/

We treat the baryon as a composite system made out of a ''core'' of th ree quarks (as in the standard quark model) surrounded by a ''sea'' (o f gluons and q (q) over bar-pairs) which is specified by its total qua ntum numbers like flavor, spin and color. Specifically, we assume the sea to be a flavor octet with spin 0 but no color. The general wavefun ction for spin 1/2 baryons with such a sea component is given and an a pplication to the magnetic moments is considered. Numerical analysis s hows that the scalar sea can provide a good fit to the magnetic moment data using experimental errors.
