Static properties of baryons in the SU(3) Skyrme model

Abstract

We study the SU(3)\ifmmode\times\else\texttimes\fi{}SU(3) Skyrme model with explicit chiral- and flavor-symmetry-breaking terms. We evaluate the SU(3)-symmetric meson-baryon coupling-constant ratio $\ensuremath{\alpha}$, SU(3) mass breaking in the octet and decuplet, and the $\ensuremath{\Delta}I=1$ part of the electromagnetic mass splitting in baryons. The theoretical numbers are in reasonable agreement with the experimental values.
