The exotic baryon mass spectrum and the decuplet-octet and antidecuplet-octet mass difference in the Skyrme model

Abstract

The octet, decuplet and antidecuplet baryon mass spectrum as a function of the Skyrme charge e and the SU(3)_f symmetry breaking parameters is given in tabular form. We also estimate the decuplet-octet and the antidecuplet-octet mass difference. Comparison with existing literature is given.
