J. Kroll et B. Schwesinger, ELECTRIC QUADRUPOLE-MOMENTS OF THE DECUPLET AND THE STRANGENESS CONTENT OF THE PROTON, Physics letters. Section B, 334(3-4), 1994, pp. 287-289
In the SU3 Skyrme model the electric quadrupole moments of 3/2+ baryon
s show a strong sensitivity with respect to flavor distortions in bary
on wavefunctions. SU3 symmetric wavefunctions lead to quadrupole momen
ts proportional to the charge of the baryon whereas for strongly broke
n flavor symmetry a proportionality to baryonic isospin emerges. Since
the flavor distortions in the wavefunctions also determine the strang
eness content of the proton the Skyrme model provides a link between b
oth quantities.
