Electric Quadrupole Moments of the Decuplet and the Strangeness Content of the Proton

Abstract

In the SU3 Skyrme model the electric quadrupole moments of ${\frac{3}{2}}^{+}$ baryons show a strong sensitivity with respect to flavor distortions in baryon wavefunctions. SU3 symmetric wavefunctions lead to quadrupole moments proportional to the charge of the baryon whereas for strongly broken flavor symmetry a proportionality to baryonic isospin emerges. Since the flavor distortions in the wavefunctions also determine the strangeness content of the proton the Skyrme model provides a link between both quantities.
