Abstract: The profile functions of the SU3 Skyrme soliton are investigated for theoctet, decuplet, and antidecuplet baryons by the mean field approach. In thisapproach, the profile functions are affected by the spatial rotation, theflavor rotation, and the flavor symmetry breaking. The solitons are stable onlyin the restricted areas of the parameter space for each multiplet. When theflavor symmetry breaking is large, the area for the antidecuplet is narrowcompared to those for the octet and decuplet. The parameters are determined bythe baryon mass spectrum, and the deformation of the soliton has sizableeffects on the masses.
