Description
The mass splittings of hyperons including the isospin splittings are calculated with $O(\ms^2)$ and $O(\ms \dm)$ accuracy respectively within the semibosonized SU(3)-NJL model. The pattern of the isospin splittings is not spoiled by the terms of the order $O(\ms \dm)$, and both splittings between the different isospin multiplets and within the same multiplet are well reproduced for acceptable values of $\ms$ and $\dm$.
